Issue in finding mpco database

[Rajkanu]

Dear STKO community,

I have been working on a simple 3D arch, but I am unable to open the output database - mpco cdata file. I have installed the external solvers from this link https://www.pucp.edu.pe/profesor/sabino ... ducciones/. When I select the solver, it shows auto-detected solvers, but they are not getting selected, so I selected manual and performed the analysis, but I couldn't get the output (postprocessing results). I have also attached the image in the zip file.

Additionally, I want to apply varying displacements (linear manner) in the longitudinal direction of the arch at each node. For this, I need to select each node. Can you please help me with how to select each node and apply displacements at each node?

Error regarding postprocessing is here

Thank you.

The output file is the *.MPCO file. The *.MPCO.CDATA file is a support file that STKO will open automatically when you open the associated MPCO file.

Hi, i have the same problem.

What do you mean?
The problem was that the user was trying to open the wrong file (mpco.cdata instead of mpco)
