First of all,my calculation environment is described as follows,
Windows7 32bits FreeCad v0.17
Since then I could do well in FEA tool(pre-post) on vesion 0.16.
Now I installed new version0.17 and tried to using FEA functions,however I could do calculate the problem and could not get result of it.
If you have a good idea,please contact to me as soon as possible.

how to set fluid dynamic FEA
My environment: windows7 32bits version 0.17
Now I have been tring the fluid dynamics by using FreeCad0.17.
However I do not know to make data procedures.
Please teach me, but I have done analyzed the problem by Fluent and AVL Fire.

for running cfd-analysis in FC please have a look at this:
https://opensimsa.github.io/
You can install the cfd-of workbench with the addon-manager (see "tools/addon-manager)
Useful video and teaching material:
https://forum.freecadweb.org/viewtopic.php?f=37&t=26826
In FC, the cfd-workbench uses bluecfd-core ( an openfoam-clone for windows).
http://bluecfd.github.io/Core/
Bluecfd-core only runs on 64-bit systems.
Can you provide your calculation to the FC-forum? Screenshots help...
Lets compare between Freecad-cfd and fluent/AVL.
regards Thomas

PLEASE teach me the way to set preference on0.17
My calculation environment: Windows7 32bits FreeCad 0.17
Problem: I could do anything to use 3D CAD however I could not use FEM workbench.
Fisrt I made the FEM Model by using FreeCAD version0.17.
Second:I changed to FEM workbench.
Third: I could set the boundary conditions and make the mesh.
Forth: I push on yello column icon and on new dialogbox I setted temporary directory and writing and calculated.
Fifth: The calculation had done.However output data was not found.
I think my preference on FreeCad 0.17 is wrong.Please inform the right preference to me.

PLease teach me capacity of FreeCAD0.17
My calculation environment: windows7 32bits FreeCadv0.17, CALculix Launcher
Now I have one problem,i.e,the warning message "out of memory".
This means lack of computer's main memory or software's capacity?
If software's capacity is meaned,please teach me overcome it.

Re: How to use FEA tools in FreeCAD 0.17
Basically our of memory means you unable to oprn a new program or file.
So you don't have enough RAM memory or to much programs open.
See: https://en.m.wikipedia.org/wiki/Out_of_memory
Don't know if the size of the mesh can do anything...
In that case saving takes a lot of time too. But you can check that easely by the file size!!

Re: PLease teach me capacity of FreeCAD0.17
Running a 32-bit operating system may be the source of this. While there are details and exceptions, roughly speaking, a 32-bit system can have memory problems because it only has 2^(32-1) memory addresses, which corresponds to about 2 GB of RAM usable for a program.Shinichi Sakabe wrote: ↑Wed Jul 25, 2018 1:37 am My calculation environment: windows7 32bits FreeCadv0.17, CALculix Launcher
