[PFEM-Fluid] new cut-PFEM element and settings
This PR introduces the cut-PFEM element among the options to chose. The order and name of elements appearing in the interface has been also changed. Finally, penalty_coefficient now appears as an input parameter of the solver.
Hi Javi! Please, check this PR and tell me if you notice something to change. Sometimes when I open more times the options of the elements I get this error/warning
I am not sure that depends on the changes I am doing in this PR.
Furthermore, I would like to add a new change but I may need your help. When the user has selected TwoStepUpdatedLagrangianVPFluidCutFemElement2D or TwoStepUpdatedLagrangianVPFluidCutFemElement3D in the interface, I would like to have automatically the following in the ProjectParameters.json:
"meshing_domains" : [{ "model_part_name" : "Body1", "python_module" : "fluid_meshing_domain", "alpha_shape" : 1.3, "meshing_strategy" : { "python_module" : "cut_pfem_fluid_meshing_strategy", "remesh" : true, "refine" : true, "transfer" : false, "reference_element_type" : "TwoStepUpdatedLagrangianVPFluidCutFemElement3D", "reference_condition_type" : "CompositeCondition3D3N" }
Instead of
"meshing_domains" : [{ "model_part_name" : "Body1", "python_module" : "fluid_meshing_domain", "alpha_shape" : 1.3, "meshing_strategy" : { "python_module" : "fluid_meshing_strategy", "remesh" : true, "refine" : true, "transfer" : false, "reference_element_type" : "TwoStepUpdatedLagrangianVPFluidElement3D", "reference_condition_type" : "CompositeCondition2D2N" },
Do you think it is possible?
Thank you for your help!
Hi @AFranci
The first part, if you have tested it and works, it's fine.
For the second query, I could not reproduce it, so send me more information if it's still a problem
For the third query, as you can see in kratos.gid\apps\PfemFluid\write\writeProjectParameters.tcl Line 299:304:307 the reference_element_type is set by tcl, so the answer is YES, it is possible to change it, BUT:
- It seem to be a loop over Bodies, and a body can contain a lot of parts, and each part be different. We can ask for all the elements applied to the body, and if there's at least one cut element, set the new value.
But I don't know if that is the expected behaviour
