Re: FEM example files miss thumbnails

great! Would it be possible to update the PR, because the FEM examples have been updated in master recently ... :oops: https://github.com/FreeCAD/FreeCAD/pull/2019 I recreated it in the new branch (since first one was in my master and during cleaning I swept it all). https://github.com/fandaL/FreeC...

Re: restrict constraint on shells

First how do you show the node points? Look at View parameter of the mesh object: "Display Mode". How i created the funny mesh? no clue. I would expect the used settings are visible in my model. In "Mesh by GMSH" i select as model 2D model and max_mesh_size =10 AND min_mesh_size=1. that's it. You c...

Re: restrict constraint on shells

Hi, I get the same error from ccx with your mesh. It contains linear quad4 elements and quadratic tria6 elements which means mid-nodes of tria cannot be connected to quads. But it is not the object of the error. incompatible_linear_and_quadratic_mesh.png It seems that nodes was written to the inp fi...

Re: working directory setting

Ok. If I understand it correctly working directory setting (in the figure) has no effect if it is already defined in preferences. For me it was confusing that something “far from eyes” has priority over what I just see on the screen. Would it be worth to inform a user during writing the inp file if ...

working directory setting

Is this a small bug or intended behavior? Open example FemCalculixCantilever3D and before writing inp file select the working directory inside Mechanical analysis (i.e. CalculiXccxTools object). Contrary to my expectations it is written to the working directory defined in Edit – Preferences – FEM. W...

Re: Material Editor in FEM

PS did you know that input pressures lower than 1Pa are rounded down to 0 ? btw Similar situation is in case of elastic modulus when writing ccx input - decimals of MPa are rounded. (Checking e.g. structural foams this is still relatively ok for my potential usage.) https://github.com/FreeCAD/FreeC...

Re: Macro Mesh Data

Code: Select all

print(mesh.Volumes)  # volume element IDs
for i in mesh.Volumes:
    print(mesh.getElementNodes(i))  # node IDs for all volume elements

Re: Macro Mesh Data

I guess you iterated through the elements with the lowest numbers, i.e. 12 edge elements and 6 face elements. But the mesh contains 6 edge elements, 24 face elements and 24 volume elements. for i in range(1,mesh.EdgeCount + mesh.FaceCount + mesh.VolumeCount + 1): print(mesh.getElementNodes(i)) # ret...
