Re: Poprawianie projektu

Generalnie lepiej nie mieszać wysokopoziomowego PartDesign z niskopoziomowymi workbenchami jak Part czy Draft. FC, w odróżnieniu od większości programów CAD, pozwala na to, co może stać się pułapką na którymś z etapów projektu.

Re: Cross section river profiles

Thanks, I was clearly blind, since I haven't noticed "Parallel cores" property in the OpenFoam tab and started editing text files;) For some reason my results are very different than yours (wrong gravity direction maybe?) and simulation couldn't go past 3,8s. https://i.imgur.com/IUs7wIS.mp4 Edit: ch...

Re: Cross section river profiles

Ok, I need some help with multithreading. I changed runCommand mpirun -n 2 interFoam -parallel to runCommand mpirun -n 16 interFoam -parallel in Allrun, but I'm getting error [0] number of processor directories = 2 is not equal to the number of processors = 16 What I have to do to change number of d...

Re: Cross section river profiles

I'm here with 8C/16T Ryzen + 16GB RAM + NVMe SSD , I can render some bigger stuff. Fell free to ask if you need some help;) @kwahoo would you consider trying to replicate (with higher resolution and longer duration) the work done by @thschrader in https://forum.freecadweb.org/viewtopic.php?f=3&t=25...

Re: Cross section river profiles

Also, @thschrader wouldn't it be awesome if there was a university or some 3rd party that would let us upload FEM related projects to process and render instead of your poor little laptop? I wonder how we could make that happen ? Is it possible to run such FEM simulations parallel on multiple compu...

Re: Poprawianie projektu

Nie ma przez polecenie Pad z PartDesign. AFAIK to ograniczenie dotyczy też większości komercyjnych programów CAD, nie tylko FreeCADa.

Da się za to przez Extrude z Part.

Re: FreeCAD w firmie

Jest gdzieś temat o poczynaniach kolegi PrzemoF w module MES? Z przyjemnością bym poczytał o jego wkładzie.
Przekop forum FEM szukając wątków "Help with testing" założonych przez PrzemoF.

Re: Poprawianie projektu

A nie ma problemów przy pracy z dwoma monitorami przy Radeonach? Żeby nie wprowadzić w błąd to pobiegłem po drugi monitor (tamten na co dzień współpracuje ze starutkim Radeonem 6670 na sterowniku R600g), wetknąłem HDMI i w ciągu sekundy miałem dwa działające monitory w trybie rozciągniętego pulpitu...

Re: [Bug] Changing a dimension in a sketch makes another sketch invalid (No planar face in the AttachEngine3D)

Thanks. I think, at this point i better to use Pad+Pocket combo instead of thickness when it's possible.
