Kratos: Error while using ParticleMechanicsApplication

[Gaoliu19910601]

Hi everyone
I am a new user to MPM applicaion in Kratos. When I try to complie MPM with DLAGRANGIAN_MPM_APPLICATION=ON, I encounter a error:

It seems that other applications like PFEM, PFEM2 could pass the complication but the MPM application could not. My system is Ubuntu18.04.

Hi @Gaoliu19910601
The LagrangianMPMApplication is legacy afaik. It was not updated for at least 1,5 years (at which we introduced what causes your error)
The current MPM-developments are in the ParticleMechanicsApplication

Hi @philbucher
So can it be used in the GID ? I can not find a ParticleMechanicsApplication in GID icon but there is a MPM application icon,

Hi @Gaoliu19910601 yes, you can generate python and json files in GiD. See https://github.com/KratosMultiphysics/Kratos/tree/master/applications/ParticleMechanicsApplication for further details on how to compile MPM in ParticleMechanics.

@philbucher @bodhinandach
Firstly,Thank you both so much for your help.. I have installed the ParticleMechanicsApplication with
-DEXTERNAL_SOLVER_APPLICATION=ON
-DPARTICLE_MECHANICS_APPLICATION=ON
But when I want to run the granularflow example, see https://github.com/KratosMultiphysics/Examples/tree/master/particle_mechanics/validation/granular_flow_2D/source
An error occured:

    KRATOS TERMINATED WITH ERROR

I do not know how to install the module named 'mpm_gid_output_process' because I can not find it in the application list. In addition, when I try to use MPM in GID by clicking the MPM icon, a error occured as:

               can't read "base": no such variable
               can't read "base": no such variable
               while executing
              "spdAux::processDynamicNodes $base"
              (procedure "spdAux::injectPartsByElementType" line 39)
              invoked from within
              "${func} $elem $ar"
             (procedure "spdAux::processDynamicNodes" line 5)
              invoked from within
              "spdAux::processDynamicNodes $root"
               (procedure "processIncludes" line 5)
               invoked from within
               "processIncludes"
               (procedure "spdAux::SwitchDimAndCreateWindow" line 8)
                 invoked from within

                  ".gid.win_example.information.img2Da instate !disabled {

                  invoked from within
                  ".gid.win_example.information.img2Da instate pressed { 
                 .gid.win_example.information.img2Da state !pressed; 
                .gid.win_example.information.img2Da instate ..."
                 (command bound to event)

Maybe there is something wrong with my operation but I do not know how to solve it.

@Gaoliu19910601 We renamed the output function from "mpm_gid_output_process" to "particle_gid_output_process". You can change it manually, or re-download or re-git-pull, as I have modified the online version. Thanks for your patient.

[Gaoliu19910601]

@bodhinandach Thank You so much, it seems ok now.
