Thanks for your response! It worked perfectly 🙂 (without even restarting Sim4Life)

You could also delete all of the model entities by filtering by type. Visible geometry objects have type 'body', so you could do:

import s4l_v1.model as model entities_to_delete = [e for e in model.AllEntities() if e.Type == 'body'] for e in entities_to_delete: e.Delete()

That worked- thanks a lot!

Mesh_material = sim.AddMaterialSettings(themesh(fromstl))
Mesh_material.Name = yourname
Mesh_material.ElectricProps.Conductivity = v # S/m

Perfect thanks !!

I am not sure to be honest why that was an issue for me with that specific version only, I installed the new version and it was there so problem solved!

In general, an easy way to create a postprocessing script is to first do it in the GUI and then use the "To-Python" function (available via right-click on the algorithm in the Explorer window).

Here is what the auto-generated script looks like for a simple pipeline with a Crop Filter:

# Creating the analysis pipeline # Adding a new SimulationExtractor simulation = document.AllSimulations["EM"] simulation_extractor = simulation.Results() # Adding a new EmSensorExtractor em_sensor_extractor = simulation_extractor["Overall Field"] em_sensor_extractor.FrequencySettings.ExtractedFrequency = u"All" em_sensor_extractor.Normalization.Normalize = True em_sensor_extractor.SurfaceCurrent.SurfaceResolution = 0.001, units.Meters document.AllAlgorithms.Add(em_sensor_extractor) # Adding a new FieldCropFilter inputs = [em_sensor_extractor.Outputs["EM E(x,y,z,f0)"]] field_crop_filter = analysis.core.FieldCropFilter(inputs=inputs) field_crop_filter.LowerExtent = numpy.array([1, 3, 2]) field_crop_filter.UpperExtent = numpy.array([21, 21, 21]) field_crop_filter.UpdateAttributes() document.AllAlgorithms.Add(field_crop_filter)

Note fyi that you don't actually need to pass a Numpy array to UpperExtent or LowerExtent, it also works if you pass any iterable, like a list or a tuple.

This is common. Once you import a script, it becomes cached so even if you make changes to it and save it, python won't see the changes. You need to reload it as you said if you make changes to the imported script after running your main script.

This looks quite good, thank you for providing your scripts.
Note that, for the second method, you could create your cylinder directly at the desired position:

cylinder2 = model.CreateSolidCylinder(Vec3(0,1,-15),Vec3(0,1,-15),0.5)

There is also the XCoredModeling.CoverWires() function that allows you to make a surface (i.e. face) out of a circle entity.

Last, but not least, note that the line model_to_grid_filter.MaximumEdgeLength is ultimately what determines the tradeoff between accuracy and computational cost of the interpolation (since it defines the resolution of the triangulated mesh on which the interpolation is done).

have you tried overwriting the E_field and raw_data variables?

Works perfectly, thanks!

Edit,
I think you could also get away with:

import s4l_v1.model as model import XCoreModeling def get_spline_length(spline): wire = XCoreModeling.GetWires(spline)[0] return wire.GetLength()

The gridding algorithms are quite different in V17 compared to V14.8, so many options simply do not have a one-to-one conversion. The best strategy is probably to learn how to use the gridder in the GUI of SEMCAD 17 (in particular the Manual Grid Settings) and then use the "To-Python" function to auto-generate the corresponding Python scripts.

I don't know V14.8 well enough to answer your other questions from the top of my head and my current V14.8 installation is acting up, so I can't help with your other questions right now. I will as soon as I fix my setup!

I had a look but also did not find it, so I added a function ConvertToPolyline which will become available in the next release (you can test it internally next week).
