@Sylvain Yes thanks finally I succeed!

Hi Andrei, I replied on the other thread: https://forum.zmt.swiss/post/1941

Hi Andrei, this error shows when there are not enough MPI-QS tokens on your license to use all cores on your computer. If parallelization is set to automatic, Sim4Life iSolve will try to use all available cores, and one MPI-QS token per core is needed. You can change the number of processes (=cores) to be used by setting parallelization to Manual and entering the number of MPI-QS tokens + 1 (solver license).

e.g. something like this def spherical_parametrization(theta: float, phi: float) -> Vec3 '''Parametrize head skin center and radius computed from head, e.g. using: p1, p2 = XCoreModeling.GetBoundingBox(skin) center = 0.5 * (p1 + p2) radius = 0.51 * (p2-p1).Length() ''' point_on_sphere = center + Vec3(radius * sin(theta) * cos(phi), radius * sin(theta) * sin(phi), radius * cos(theta)) r = XCoreModeling.GetEntityPointDistance(skin, point_on_sphere) return r.ClosestPosition This should work quite well, except for the concave regions, e.g. behind the ears.

I typically do the following (which also clears the history and frees memory): import XCoreModeling as xcm xcm.GetActiveModel().Clear()

Here is a simple implementation to write an iSEG tissue list file, given a dictionary mapping the label index to a name: https://github.com/dyollb/s4l-scripts/blob/df8e2241f87ca91d71138e9d2b3d4336dadb82dc/src/anisotropic_conductivity/load_labels.py#L44

have you tried overwriting the E_field and raw_data variables?

Dear @NaraSakamoto Thanks for your feature suggestion.

Hi Jack, no, it is not possible to "borrow" a license

Hi Abdou, this could happen if there are some libraries missing. Reinstalling the SW with the default options will help.

@bryn Thank you again for your reply and the posture file!

Hi @bryn, I'm meshing an implanted device as a faceted mesh which is then embedded in an octree mesh. This is all through the Python API.

This screen capture shows how you can then move/snap the "Spline Control Points" (the little white dots) to the offset surface: https://youtu.be/kveLjnKpWzU

Hi @Paul_fgp Could you please share any error messages you have received? Thanks

Dear Ali, It looks like the path to iSolve is not set correctly. Please follow the steps below: Open Ares on the machine where Sim4Life is installed Click on the blue cross at the end of the line labeled "Paths to the iSolve solver executables." This will open a pop-up window. (see the image below) If the list of solvers is empty or the one you intend to use is not listed, simply add the path to the relevant solver. Restart Sim4Life.

Thanks, the simulation file is from sim4life V7.2, so I'm not able to see the convergence in the analysis window. Fortunately, I have found the "x_Output.log" in my Results file, but I can't understand it. Could you please explain the meaning of each row in the results file? Take an example like this: Sensor 'Capacitor_L 1 (Current L)' Exponential moving average factor 0.894427, Harmonic steady state detector: time step 3.08414e-10s, frequency 64MHz, approximate quarter period 3.70097e-09s, target convergence level -50 dB Iteration number and conventional convergence level in dB <raw> <ema> [<raw> <ema> ...]: 16800 13.9358 1.47124 8.4181 0.888723 18816 7.67597 2.12629 15.5107 2.43241 20832 14.0806 3.38834 13.5789 3.60917 22848 1.26816 3.16451 7.74689 4.046 24864 4.59394 3.31542 3.89595 4.03016 26880 -2.64392 2.68627 0.958616 3.70589 28896 0.107048 2.41398 -1.53674 3.15241 30912 -4.9591 1.63558 -3.76506 2.42211 32928 -2.79052 1.1683 -6.11092 1.52126 34944 -5.90745 0.421296 -8.34643 0.479498 36960 -4.81187 -0.131184 -10.7496 -0.705992 38976 -5.89793 -0.739996 -13.7845 -2.08673 40992 -6.1714 -1.3134 -17.1553 -3.67755 43008 -5.32482 -1.7369 -21.5846 -5.56806 45024 -6.82203 -2.27375 -32.324 -8.39276 47040 -2.12306 -2.25784 -15.5315 -9.14641 49056 -0.278664 -2.0489 -3.5348 -8.55398 51072 -6.34679 -2.50264 -2.30536 -7.8943 53088 -0.399402 -2.28059 -2.38639 -7.31281 55104 -9.37643 -3.02972 -4.00497 -6.96359 57120 -29.014 -5.77295 -18.2975 -8.16015 59136 -55.4153 -11.0138 -31.9566 -10.6724 61152 -57.6383 -15.9361 -37.9006 -13.547 63168 -58.9883 -20.4813 -26.9761 -14.9647 65184 -58.6026 -24.5058 -39.9291 -17.6003 67200 -57.9518 -28.0368 -37.4931 -19.7004 69216 -59.1574 -31.3223 -36.9919 -21.5259 71232 -59.0974 -34.2546 -28.7893 -22.2927 73248 -59.633 -36.9339 -25.1269 -22.592 75264 -59.2213 -39.2868 -31.2338 -23.5043 77280 -59.5994 -41.4313 -27.1446 -23.8886 79296 -59.9846 -43.39 -25.5704 -24.0662 81312 -61.3968 -45.291 -28.9199 -24.5786 83328 -61.7502 -47.0287 -26.6773 -24.8002 85344 -61.0201 -48.5058 -30.0321 -25.3525 87360 -61.1226 -49.8378 -25.216 -25.3381 89376 -63.0251 -51.23 -33.6491 -26.2155 91392 -66.6494 -52.8579 -33.5 -26.9845 93408 -67.4893 -54.4026 -29.6102 -27.2617 95424 -70.0935 -56.0591 -29.03 -27.4484 97440 -71.562 -57.6958 -27.7633 -27.4817 99456 -69.5748 -58.9499 -26.854 -27.4154 101472 -78.6 -61.0244 -28.1287 -27.4907 103488 -67.7923 -61.7389 -25.6139 -27.2926 105504 -68.4293 -62.4452 -23.2911 -26.8701 107520 -65.0311 -62.7182 -24.074 -26.5749 109536 -65.161 -62.9761 -31.2989 -27.0737 111552 -65.5676 -63.2497 -29.642 -27.3448 113568 -61.3018 -63.0441 -27.2672 -27.3366 115584 -60.839 -62.8113 -26.1289 -27.2091 117600 -60.3076 -62.5469 -27.3216 -27.221 119616 -61.3064 -62.416 -26.3063 -27.1244 121632 -62.103 -62.3829 -28.0492 -27.2221 123648 -61.1791 -62.2558 -34.3984 -27.9797 125664 -61.6997 -62.1971 -24.1963 -27.5803 127680 -60.7142 -62.0406 -27.5361 -27.5756 129696 -62.5137 -62.0905 -28.7848 -27.7033 131712 -62.9527 -62.1815 -28.8431 -27.8236 133728 -63.5879 -62.33 -27.4008 -27.779 135744 -63.518 -62.4554 -27.3935 -27.7383 137760 -66.5672 -62.8895 -37.3044 -28.7482 139776 -66.7306 -63.295 -28.7205 -28.7453 141792 -66.0728 -63.5883 -24.7314 -28.3215 143808 -67.7974 -64.0327 -24.6679 -27.9358 145824 -69.0101 -64.5581 -25.0781 -27.6341 147840 -67.3162 -64.8493 -16.4316 -26.4514 149856 -66.9178 -65.0677 -21.271 -25.9045 151872 -72.7687 -65.8807 -28.3618 -26.1639 153888 -69.2686 -66.2384 -21.0304 -25.622 155904 -68.7916 -66.5079 -17.7813 -24.7942 157920 -65.0066 -66.3494 -19.2192 -24.2056 159936 -68.1325 -66.5377 -26.2937 -24.4261 161952 -64.7744 -66.3515 -23.2103 -24.2977 163968 -68.9681 -66.6278 -21.4553 -23.9976 165984 -67.3859 -66.7078 -18.5064 -23.4179 168000 -66.1211 -66.6459 -23.847 -23.4632 170016 -67.4045 -66.726 -19.9166 -23.0888 172032 -65.1708 -66.5618 -25.465 -23.3397 174048 -68.6925 -66.7867 -22.8274 -23.2856 176064 -67.0903 -66.8188 -25.4394 -23.513 178080 -64.5303 -66.5772 -19.6368 -23.1038 180096 -64.284 -66.3351 -20.7205 -22.8522 182112 -64.9833 -66.1924 -22.9353 -22.8609 184128 -64.2102 -65.9831 -17.2516 -22.2687 186144 -61.8411 -65.5458 -18.5849 -21.8798 188160 -67.4312 -65.7449 -22.0218 -21.8948 190176 -63.0463 -65.46 -29.3056 -22.6772 192192 -73.1833 -66.2753 -18.072 -22.191 194208 -62.5461 -65.8816 -17.785 -21.7259 196224 -66.6467 -65.9624 -21.6314 -21.7159 198240 -63.3296 -65.6845 -23.0527 -21.857 200256 -66.4044 -65.7605 -26.6222 -22.3601 202272 -66.1052 -65.7969 -25.6971 -22.7124 204288 -63.9959 -65.6067 -19.0422 -22.3249 206304 -67.4349 -65.7997 -26.79 -22.7963 208320 -65.1095 -65.7269 -26.0593 -23.1408 210336 -68.519 -66.0216 -24.4157 -23.2754 212352 -65.3768 -65.9536 -18.3469 -22.7551 By the way, what's the meaning of "convergence", and which value or formula do we use to express this variable?
