Re: FEM anaylsis of GDML Designs.

Not sure what has changed but I still get the message, but it does now create a Mesh. I will experiment to see if I can reproduce the problem again. What is the situation with Compounds of different materials, can one still do FEM analysis on them ? How does one specify the material of each object? ...

Re: FEM anaylsis of GDML Designs.

Okay I tried to see if I creating a Mesh for a simple GDML Object i.e. implemented as a FreeCAD Python Object. When in FEM workbench. Have it selected then click on Mesh icon window pops up with Apply | Cancel | OK but before I get to try Apply I get a message in Report View Fem::FemMeshObjectPytho...

Re: FEM anaylsis of GDML Designs.

Okay suppose I add a function that scans down a Volume ( Part ) and creates a compound that I attach to the hierarchy under the selected Volume/Part. Could one then switch to the FEM work bench, then select that compound and go from there?

Re: FEM anaylsis of GDML Designs.

This is an example of a file that is more than one object but not too complex. structure.png I don't really want to have to learn how to use FEM to test this out as I already have too much on my plate. If you could advise or test out that would be great. All GDML files have a World Volume ( implemen...

Re: FEM anaylsis of GDML Designs.

Fully aware that FEM needs to produce a MESH for analysis. I assume that the programs that produce Meshes take as input a single Part. Now with an imported GDML file, things are under a Part ( World Volume ) but within Parts they can be separate Objects and the Objects are all FreeCAD Python Objects...

Re: Qt Applications

There is a QT application that has some function that I like. I would like to have a FreeCAD Workbench function that opens a new window which the QT application/code controls. When it closes the Window I would like it to pass me some info that I can then use via python to perform functions in the wo...

Qt Applications

I know FreeCAD uses Qt so could one take parts of a Qt Applications and add them to FreeCAD?
What interfaces are available between native Qt and FreeCAD?
Where is this documented?

Thanks

FEM anaylsis of GDML Designs.

I am in the process of developing a GDML workbench see https://github.com/KeithSloan/FreeCAD_Python_GDML Currently a number of GDML solid types are supported. The GDML Solids are implemented as FreeCAD Python Objects. The main purpose of a GDML design is for Monte Carlo Particle analysis (which need...

Python scripted object as part of a boolean.

Okay I have a python scripted object and when a user changes one of the parameters the onchange function of the objects class gets driven and I can perform the appropriate redraw. Now how do I handle the situation if the object is part of a Boolean? i.e. How do I get the boolean to redraw? Note: I n...
