Hello everybody,

I have a couple of mesh database files (.mshdb) and I want to convert all of them to CGNS in an automated process. I’m using ANSYS 2021 R2. I cannot use PyMechanical unfortunately, and no matter what I do with ACT, using Journal, using CFX-Pre, or using Fluent, it’s not working. I can convert them manually one by one, but I’m just wondering if there is a way to do it in batch mode or using IronPython or any other ideas.

Thank you.

Solved by myself:

Not fully automated (like APDL and batch script) but still working. I used WB, File --> Scripting --> Run script --> choose python code (Iron python code!). First upload the project

Open(FilePath = Wbpj_path)

Then set current design point to 0 (dp0) and update the mesh (I learned this one by recording Journal from File)

dp0 = Parameters.GetDesignPoint(Name= "0")
Parameters.SetBaseDesignPoint(DesignPoint=dp0)

Note that if dp0 is already set as current design point do not runParameters.SetBaseDesignPoint. The code will give you an erro stating the dp0 is current and exit (which I found it so dumb)

Anyways updating Mesh:

# Update Mesh
system0 = GetSystem(Name="SYS")
meshC0 = system0.GetComponent(Name="Mesh")
meshC0.Update(AllDependencies=True)

here is get tricky you need to choose Mesh container and open it and then export your mesh.

mesh1 = system1.GetContainer(ComponentName="Mesh")
mesh1.Edit()

export_command = '''DS = WB.AppletList.Applet('DSApplet').App;DS.Script.doFileExport("F:\dump_here\SYS.cgns")'''

# Execute
mesh1.SendCommand(Command=export_command)

and finally exit

mesh1.Exit()

Of course at the beginning import os and use For loop to loop over all desgin points. You can use this method to save the mesh to other format as well.
