a2e473c5b7 [FEM] Elmer: set constraints for solver systems
- set constraints according to the Elmer docs (no conversion necessary, existing properties just stay integers)

d985525893 [FEM] Elmer: just sorting to keep the overview 2022-08-14 01:07:11 +02:00

b6cb5ffe4a [FEM] Elmer: fixes for multi-threading
- load the results depending on the used cores, not always the multi-thread results
- avoid unnecessary console output - this info is already output in tasks.py
- handle number of cores as int to save in total 2 conversions

08af39c1a8 [FEM] Elmer: fix heat flux handling
- the heat flux in the temperature constraint is not the heat flux from the heatflux constraint. The latter is in W/m² while the first one is W/mesh node

2edf6abb2f [FEM] Elmer: add support to turn off solvers
- with this property the linear solver is turned off. As consequence one can this way also disable the execution of an equation without the need to delete the equation object

- also add missing preconditioners

b716644e27 [FEM] Elmer: fix handling if fluids + solid materials
- as already reported in the forum, it was not possible to make a flow simulation when there is also solid material.

ed3625a0e0 [FEM] Elmer: allow lower relaxation factor
- despite the Elmer docs say 0.01 is the lover limit, for fluids like water, one might need down to 1e-4

ad2042e3cb [FEM] electric Potential: add missing conversion

c219134a1e [FEM] Elmer: fix material bug and improve material handling
- for fluid material writing the elasticity solver failed with unknown Young Modulus
- fix regression with checking for fluid material. Checking the material of the bodies is not sufficient. One can e.g. have a solid without bodies defined, then it applied to all bodies and there might be a fluid defined for only one body. Checking the body's material would then deliver there is no fluid

baaa5f8dd1 [FEM] Elmer: set constraints for relaxation factor
- the relaxation factor is crucial for nonlinear systems thus help the user by setting constraints and convenient steps.
Since the property stays a float no update is necessary, existing properties just stay a normal float

48a206e3e4 [FEM] Elmer: notify users about missing fluid material
- it was often unclear when no flow equation was written to the case.sif (was a regression FC0.20)

69efa37e49 [FEM] Elmer: automatic update for BiCGstablDegree
- up to last week we used the invalid BiCGstablDegree 0 thus update to the default of 2

a32e927227 [FEM] Elmer: scale EigenMode results
- for an not yet known reason the result from Elmer are only for eigen analyses a factor 1000 (we send the mesh scaled to Elmer and it seems the eigen solver does not notice this)
Therefore scale these results

d438514d9f [FEM] fix pipeline recompute issue
- after a simulation was run, the pipelines and its childs are recomputed but its shape coloring is not updated.

- also update XML documentation
- also remove comment in tasks.py for now

8b06680eb8 [FEM] add framework to scale result mesh values
- it seems that we will need to scale result values (probably for the Elmer Eigen solver)
  This PR adds the framework to do this. It is meant for Elmer but designed versatile.

90afc19382 [FEM] fix pipeline recompute bug
- on recomputing scalar or warp filters the information about the field was lost.
  This is because the validity of an array was tested before it is actually filled

- also fix MSVC warning of using a C++ keyword as variable
- also avoid an unnecessary recompute after Elmer solver was run

460efa3a72 [FEM] Elmer: use defaults of ElmerGUI
- use also for the linear solver the defaults of ElmerGUI

753a034708 [FEM] Elmer: fix for electricforce
- the default is to execute this solver after previous solution converged. This has to be output via the Exec Solver parameter

38aaf9bfb3 [FEM] Elmer: fix pipeline update issue

e4e34affac [FEM] Elmer: resale the mesh using Elmer
- according to Peter from the Elmer team, we can use Elmer for both, scaling in and scaling back just for consistency

dcdbf6dcaa [Fem] Elmer: change default nonlinear tolerance
- ElmerGUI uses 1e-7 as default, so we should do too

3d0def93cd [FEM] Elmer: fix default for heat
- revert change from comm it commit f3933016 - "None" is the correct default. (I mixed this up with Navier-Stokes)

81836aae11 [FEM] Elmer: polishing for nonlinear system
- add tooltips
- relaxation factor is usually not below 0.1 thus no expression is necessary
- sorting

84db9d4baa [FEM] Elmer: fixes for electrostatics

- add electric flux to point filter results
- add missing parameters
- also some sorting

f39330163d [FEM] Elmer: code improvements
- don't redefine lists twice
- also fix mistake for heat - the default is computed convection

b621e6c253 [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

b5a34817db [FEM] Elmer: fix mistake with transient solving
- there is proper info, just in another Elmer manual. This unveiled my mistake - the timestepping parameters are a list

3818534cd6 [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
2022-08-06 04:32:18 +02:00

cd03ef3d78 [Fem] Elmer: don't output unused parameters
- many of the new parameters don't have to be output if they are not used

- also some sorting

96ba47e80f [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

18d1941a79 [FEM] Elmer: push mesh scaled to Elmer
- reverts commit d296732d - the scaling it correct
- there is a bug in Elmer that the heat source is not aware of the scaling
- write the scaling directly to the solver, not to the mesh itself. (make in principal no difference but we are closer to the solver)

Uwe
357989c552 [FEM] fix enable editing for all solvers
- currently for Z88 nothing happens when clicking the Edit button in the solver task dialog. The reason is that opening *.txt files was never implemented
- also do this for Elmer
- for Z88 we need to open several file for a proper editing because the solver info is distributed over these files

0549a47b09 [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)
2022-08-04 03:57:46 +02:00
Uwe
82f41ce220 [FEM] Elmer: setup new pipelines like we do for CCX
and manually new created ones

d455ba378e [FEM] Elmer: use different default linear solver
