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).

You're welcome! Note, however, that functions that are not part of the s4l_v1 module are not checked for backward compatibility between Sim4Life versions and their signatures are in principle allowed to vary (although this is quite rare, in practice). It is recommended to always try to use functions under the s4l_v1 module when possible, since only these are "officially" part of the API. This said, if you need to bend an object in Sim4Life v4.x or lower, use XCoreModeling.PlanarCut :-)

Thanks so much!

@sylvain Never mind, I figured it out why. Thanks anyway

@sylvain Yes! thx

In Matlab, you can reshape the Snapshot0 quantity in the following way. For cell-centered data with 3 components (e.g. Electric field E(x,y,z)): E = reshape(Snapshot0, [length(Axis0)-1, length(Axis1)-1, length(Axis2)-1, 3) which you can then use as: E[i,j,k,c] where c is an index to the field component and i,j,k are indices to the discretization of space. For point data with 1 component (e.g. Vector potential V(x,y,z)): V = reshape(Snapshot0, [length(Axis0), length(Axis1), length(Axis2)) which you can then use as: V[i,j,k] where i,j,k are indices to the discretization of space.

The function you are looking for is LinkMaterialWithDatabase(). This is how you can add new material settings with properties taken from the database import s4l_v1.document as document import s4l_v1.model as model sim = document.AllSimulations[0] for ent in model.AllEntities(): mats = sim.AddMaterialSettings([ent]) mats.Name = ent.Name sim.LinkMaterialWithDatabase(mats, str(ent.MaterialName)) To modify the settings of an existing simulation and update their properties, you can do something like this: import s4l_v1.simulation as simulation material_settings = [s for s in sim.AllSettings if isinstance(s, simulation.fdtd.MaterialSettings)] for mats in material_settings: material_name = mats.Name sim.LinkMaterialWithDatabase(mats, material_name)

sorry, I gave you some code for the Simulation Combiner, not the Field Combiner... This is how you can use the GetWeights and SetWeights functions for the field combiner: >>> field_combiner.GetWeights() ((1+0j), (1+0j)) >>> field_combiner.SetWeights( ( (2+0j), (-3+0j) ) )

There is no python interface for the Solid Cone creation tool. However, you can achieve the same result by using the SkinWires() primitive as follows: import s4l_v1.model as model import XCoreModeling c1 = model.CreateCircle(model.Vec3(0,0,0), model.Vec3(0,0,1), 50) c2 = model.CreateCircle(model.Vec3(0,0,50), model.Vec3(0,0,1), 25) XCoreModeling.SkinWires([c1, c2])
