How to get post-processing results with Gmsh SwiftComp GUI

Hello everyone.

I'm trying to perform several multiscale analisys jobs for textile structures. As a result I need both stiffness data (which can be generated directly in TexGen4SC) and relative strength properties, for example I'd like to see in which structure will be highest stress in composite matrix upon equal loading. 

To do the second part of wexperiment I launch SwiftComp tool, import there SC. file which is generated with TexGen4SC and then perform homogenization and dehomogenization. As a result I get a voxel mesh in post-processor. So, now I need to see my textile structure as pack of separate parts - yarns (there are several materials of fibre in my tasks) and matrix. And I didn't find any pre-set GUI feature to select parts of mesh, only it's possible to hide elements by number.

So, the question is: is there in default SwiftComp GUI an utility to hide/show mesh parts according to it's material data? and if not, is there any simple way to solve my problem?

Thanks!

    Hi Ivan,

    This is a very good question. The online SwiftComp GUI or Gmsh4SC is built on gmsh, so the question is whether gmsh can visualize the results by groups. Based on my knowledge, the answer is no. In you case, you need to do some codings yourself. All the stress results are stored in .sn file, which are arranged element by element. You can also find the element information to see if it belongs to matrix or yarn in .msh file. So you already have all the information you need.

      Thanks for your reply!

      So, the following question is how to organise data transfer from cdmHUB internal file system to my PC and back. Is it possible, or i need to request and setup local versions of TexGen4SC and SwiftComp?

        map a network drive to https://cdmhub.org/webdav, with your username and password, then you should be able to find the data folder and corresponding sessions, and you can drag and drop files between your pc and the cdmHUB.

    In Abaqus SwiftComp GUI, you can use the 'visualization' button to create an .odb file from the .sc, .sc.sn, .sc.u files and then visualize the displacement, stress and strain in Abaqus, then you can use some python scripts of Abaqus functions to create sets or groups of elements in the odb file and do more calculation and evaluation to the different sets, as mentioned by Xin. This maybe the easiest way I can think of to visualize the results of stress and yarns.

      Ok,

      so it's only possible for local (offline) version of software?
