interpolation function alternative

Please login with a confirmed email address before reporting spam

Let's say I have a 3D model with 10x10x10 blocks. I need each block to have different conductivity.
I tried to create different material (where each material corresponds to each block), but comsol after a few materials, just freezes.


In one initial approach, I can define an interpolation function with x,y,z coordinates and conductivity values, imported from a txt file.
If I use the coordinates of the center of each block, then I don't get to assign a uniform value to the whole block.
If I try with giving coordinates of the nodes of each block, then I have duplicate points.
I can try not to give the exact node coordinates, but just slightly small, so I can avoid the duplication. This approach makes the interpolation function, computational heavy.

Is any other approach I could use?
