[amscosta]

Hi,
The following error message is happening when trying to run svpre for a .svpre from the simulation database:
Any clue how to start working on the issue is very welcome.

@amscosta The svpre program is used by the svSolver.

There are a couple of SV Forum posts about this problem.

You didn't mention which OS you are using but it you are using Ubuntu 20 or 22 there is a known problem with the expat library used by VTK.

You can try

 sudo apt update

or if that doesn't work then run the following to install an earlier version of expat.

sudo apt-get install libexpat1=2.4.7-1 libexpat1-dev=2.4.7-1
