Re: GSOC 2019 Thread (DEADLINE: FEB 6th Mentor Organizations Applications Due)

Hi Yorik,
I am also in if you need someone for mentoring fem related topics like testing solvers.

Re: Flowsimulation in a tube

Hallo sirpete83 and HoWill, I have an identical case for my Master Thesis and I am stuck since days, so I am asking you for help. I need to simulate a waterflow through a box filled with stones and see, how the pressure changes before and after. The Problem is that I am not even capable of generati...

IMHO if Ol's big logo looks good than small doesn't. Old one is more readable.
Why not ping agryson ?

Re: FEM Thermal Analysis of a PCB: a new challenge

Also my 2 cent. 8-) - To simulate such PCBs in a meaningful way we need convection :!: :mrgreen: -- Convection is available as boundary-condition in calculix (also done in simscale) but not jet implemented in freecad. I somehow remember that this boundary condition is not really accurate but do not ...

Re: Elmer solver unit scaling

Dear Gerald, Elmer software was designed to accept all inputs as SI units. As a result any interfacing to Elmer should use SI units. As Wilfried stated it looks like the examples work. This is because FreeCAD exports all the material properties scaled to mm scale. For some simple simulations (from t...

Re: Elmer solver unit scaling

I found some issues with unit scaling using Elmer solver. The generated UNV file used as an input for ElmerGrid tool as node coordinates as mm. Hi Gerald, I am pretty sure that you do not have to fix a thing. You are right that FC uses mm as base units and the model is exported in mm as base units....

Re: Flowsimulation in a tube

Hallo, I try to use the Elmer Solver for a simple water flow simulation. I have attached my file see below. everything seems to be fine, but all the boundery conditions are ignorred at the moment when creating solver file. Maybe someone knows how to use this new functionallity Thanks a lot Peter Hi...

Re: Fenics as Solver

I will test it. My conjecture is that due to inner and outer surfaces at inner boundaries and when you multiply each area element with some inner and the corresponding outer normal vector, their sum is identically zero. Maybe to correct this behaviour we have to make those boundaries real outer bou...

Re: ui improvements

see post before your post ... :mrgreen: I just love it :!: :D Do you think it is possible to store such section-views as element in the object tree? Finally, to save some clicks it would help if you would incorporate this as tick-box into the selection dialogue for solids. Thank you so much, HoWil ...
