Re: bugs in tutorial no. 8

If I only have nonlinearelasticity.xml in my edf folder than it works if I put both linearelasticity.xml and nonlinearelasticity.xml in my edf file than the properties from the library get divided up between the two. Thanks for this analysis. Should I open an issue in GitHub or how can I report the...

Re: How to get the MUMPS solver on Windows OS?

For direct you could use Umfpak or banded, or switch to an iterative solver. Unfortunately not because most CPUs have 8 ore more cores. Using only one CPU core is slow and for multi-CPU solving you cannot use Umfpak. MUMPS: https://mumps-solver.org/index.php is not available as free download. You c...

Code: Select all

Vtu Time Collection = Logical True
It will create additional .pvd file that contains timestep information of each vtu file.
Many thanks! This is what I needed.
(This way I could eventually provide proper transient solving support for Elmer via FreeCAD.)

Re: Output Intervals logic is wrong

Output Intervals(2) = 2 2 Timestep intervals(2) = 2 2 Timestep Sizes(2) = 0.05 0.02 should give me just 2, but I get 3. OK, I get it now: the interval always begins with 1. So in every case you get a result for the first time of an interval. The third result is the final one. I also struggle to und...

bugs in tutorial no. 8

when doing tutorial no. 8 "Non-linear elasticity equation –3D ", I noticed these 2 issues: - the simulation cannot be run because the Poisson ratio is undefined. To fix this, the material "Austenitic stainless steel (AK Steel 201)" should get a Poisson ratio or the manual has to ...

Re: two mistakes in Tutorial no. 14

The forum doesn't send notifications, and hasn't for several years. Can this please be fixed? We use phpBB for FreeCAD and it can send emails. For example, I could not login, tried to change my password, but since the forum does not send any emails, one cannot change the password once one has it fo...

Re: two mistakes in Tutorial no. 14

Point 2, I'm coming up with an imaginary B of 0.0052 T. I added a Saveline solver, and that's the result at the surface of the wire at radius = 0.001 meters. Hi Rich, sorry for the late reply, but the forum does not send me any notifications despite I enabled them. To the issue number 2: you get 0....

Re: BodyForce error for Heat Equation

Yes. We could also add bodyforce:real:temperature to SOLVER.KEYWORDS. Thanks. Please do so. By the way, why don't I get any notification from the forum. I checked my settings and I enabled everything, but neither on my topics nor on threads where i posted, I get a notification email. Can anybody pl...
