Re: How about a general FemMaterial.py to suport Mechancial, Thermal, Fluidic and ElectroMagnetic

I see in some of the freecad wiki documentation that the proposed format for the documentation of material properties was xml ( http://www.freecadweb.org/wiki/index.php?title=Material_data_model ). So I was just wondering if all the materials somewhere in the future could be standardised in the non-...

Error when using displacement constraint with split input file

This is a fix on an error that occurs when you use displacement constraints in the absence of fixed constraints and write a split input file. The cause of the error was the omission of certain lines of code dictating the inclusion of the displacement constraint and the plane rotation constraint node...

Re: Split writing of input files

How about this?

I tested it and it works like a charm. If everyone is happy we can maybe put in a pull request to get it into the main branch?

Re: Split writing of input files

- the main files uses absolute paths. We should use relative path, to be able to move the whole CalculiX analysis somewhere else I do however have one question on this suggestion. I assume this relates to the line of code in the FemInputWriter.py file that reads: self.file_name = self.dir_name + '/...

Re: Split writing of input files

- if some constraints are not used empty files are created. We should not create empty files - the name of the main file should have some "main" or whatever to distinguish from not spited analysis. - The "Node" in file name seams wrong for Elem_sets and Pressure IMHO Would it no...

Split writing of input files

The writing of the input file for the solver CalculiX have been split so that the node sets for the different constraints are written in individual files and then imported into the main input file. This removes the cluttering of the input file by long lists of nodes to ease its editing within Freeca...

Re: Fem constraint contact

Hello, this is now split into three sections which are all working. 1: Thermo-mechanical analysis 2: Contact constraint 3: Plane-rotation constraint https://github.com/makkemal/FreeCAD/tree/rtd_vdwalts Work in progress: 4: Split of input file writer Tested up till point 3. Thermo-mechanical added a ...
