c4097ede8f [FEM] Elmer: fix default for heat 
- revert change from comm it commit 117d789e - "None" is the correct default. (I mixed this up with Navier-Stokes)

0b969fbc0a [FEM] Elmer: polishing for nonlinear system 
- add tooltips
- relaxation factor is usually not below 0.1 thus no expression is necessary
- sorting

f7099cd43c [FEM] Elmer: fixes for electrostatics 
- one needs to specify a file when calculating the capacitance matrix
- add electric flux to point filter results
- add missing parameters
- also some sorting

25c33ade64 [FEM] Elmer: code improvements 
- don't redefine lists twice
- also fix mistake for heat - the default is computed convection

057a19af82 [Fem] Elmer: output the equation-specific settings 
- equation-specific things were not set at all. This is the first step for the heat and Stress equation

40629bb2bf [Fem] Elmer: update tolerances 
- update tolerances also for existing analyses to fix the bug that users see e.g. "0.001" and not the actual used tolerance
- also a fix for new stress analyses
- also a formatting fix

125d2962c7 [FEM] Elmer: next step to fix eigenfrequency analysis 
- add missing parameters to perform modal analyses
- set mandatory complex statement

0567a7c026 [FEM] Elmer: fixes for the simulation parameters 
- output equation-specific values only if this equation is used
- use Elmer's default for BDF order as default for FC too and allow to change it
- don't hardcode to Steady State. Transient must be possible too, this way add parameters to run a transient analysis

fce9a2fcfb [FEM] Elmer: add missing parameters for flux equation 
- also add tooltips

a046c1aaa6 [Fem] Elmer: add missing settings for the stress solver 
- the usually mandatory setting DisplaceMesh was missing leading to imprecise results. Now the calculated faceload is almost the exact same as with CCX
- also add most of the other settings Elmer 9 provides
- also add tooltips
 2022-08-05 04:17:39 +02:00

34e45fbcac [FEM] Elmer: more work on Stabilize 
- it turned out that despite not mentioned in the manual, ElmerGUI adds the Stabilize setting for all setups
-> bring "Stabilize" back for all equations
(for "Bubbles" it is correct that this is an equation-specific setting)

e4d1cb66e9 [FEM] Elmer: use different default linear solver 
- BiCGStabl is as robust as BiCGStab but in all tested cases it converges faster
 2022-08-04 03:24:03 +02:00
Uwe
5d1b25f130 [FEM] Elmer: use direct solving as default for stresses 
- direct solving is sometimes even 10 times faster (as fast as CCX) and as accurate as CCX

bbc21b336a [FEM] Elmer: fix solver stabilize settings 
- according to https://www.nic.funet.fi/index/elmer/doc/ElmerModelsManual.pdf
the stabilization methods are equation-specific and only available for some solvers
This commits changes these settings according to the manual

a6288fdabe [FEM] Elmer: Flux: add missing settings 
- enable the disabled options. They work and are according to the Elmer manual. The user is free to use them or not and since they are all False by default, existing analyses won't be affected.
- add two missing settings
- for new equations, enable at least one calculation, otherwise nothing will happen when an inexperienced user uses the default

927cecc742 [FEM] Elmer: set sensible defaults for elasticity equation 
- for BiCGstabl the minimal degree is 2, but 3 is recommended
- when adding the equation, it should do something, therefore enable the calculation of the principal stresses (as it was, nothing was calculated except of the displacement)

- use an expression as discussed: https://forum.freecadweb.org/viewtopic.php?p=613897#p613897

52b2bc6e38 [FEM] Elmer: add missing direct variant MUMPS 
- also use capitalized wording to Umfpack as Elmer does
