I am using OpenSees for dynamic soil–structure interaction analysis and ParaView for post-processing the results.
My model contains quad soil elements and structural elements. The VTK output works correctly in ParaView when no absorbing boundary elements are used.
However, after adding ASDAbsorbingBoundary elements, ParaView cannot read the generated .vtu files and gives the following error:
Cannot read point data array “Disp” from PointData in piece 0.
The data array in the element may be too short.
The error is repeated for the time steps.
I am using:
recorder vtk NPP_Results disp accel -dT 0.002
Is ASDAbsorbingBoundary fully supported by the OpenSees VTK recorder? Could these elements cause an inconsistency between the number of mesh points and the Disp PointData array?
What is the recommended way to export an OpenSees model containing ASDAbsorbingBoundary elements to ParaView?
There’s nothing obviously wrong with the “Disp” data array definition in the XML file at first glance. The number of values looks to be right. I would need to dig in deeper to see what’s going on.
