visualSHysics foamsimulator
Hi to everybody.
I' tryng to use Freecad Pre19 to make some first analysis, and I should like to render results with visualSHysics in Blender.
Anything seams to work well, except FoamSimulator: it fails saying that .xml file isn't of the right release.
Because Freecad add-on release is v4 (or v4.4, I don't know exactly) , is this the problem?
Many thanks
Piero
Comments
Hi Piero,
could you please share a screenshot of the error message?
Regards!
Thank you for your fast replay.
Here is the copy of command shell (it was made in Ubuntu 18.04, using Blender 2.91):
I tried two times to start the Run Foam Simulation command, but I don't know why the error message was duplicated for each execution attempt.
Again, I'm attaching the starting Float2_def.xml file, made using Freecad 0.19 pre.

Hi Piero, I think that the problem is that you are using the Float2_Def.xml file instead of the Float2.xml file generated by the gencase tool. The second one has some calculated constants needed for the foam simulation.
Hi to everybody,
I tried again in these days, but th answer is always the same (loot at the attache picture).
This time I'm sure that I used the right .xml file, calculated by Gencase rev. 5.03.
Perhaps the difficulty is created because I built the case in Freecad:
1) I built the case in Freecad and I used Gencase and run the case by Freecad Interface
2) I used an external script to calcolate all post-processing files
3) finally I went to Blender to load al needed files
But it still doesn't work !!! 😭
Thank you again
@Orlando may help here
Hi Alex,
sorry, but I don't understand: what could I do? can I write directly to Orlando?
Many thanks
Piero
I mention orlando here so he should receive notification about this message...
Other option is to contact him directly if you want: orlando@uvigo.es
Regards
Hi to all.
Perhaps I found the problem: the file Float2_Def.xml generated by Freecad interface begins with a comment line, like this:
<!-- Case name: Float2 -->
and this first row is copied to the file Float2.xml created Float2_out directory: to perform a correct foam calculation is enough to delete this first row saving the file again.
And this is all.
Just a suggestion: is it possible to avoid to write this first row during GenCase phase in Freecad?
Many thanks to everybody. Regards
p.s. How is possible to write "SOLVED" near to the title?
Nice work @pier_1251! I had given up on the foam simulator tool, since I couldn't get it to work
I just wonder what my issue might have been then, since I am not using FreeCAD for generating the models. Perhaps I will look into my case again some time.
Also I do not think it is possible to write "SOLVED" near the title as of now, but perhaps could be a nice addition to the forum @Alex ?
Kind regards
