Hi Admin,

I am using STKO for post-processing in my current analysis. I have created a TCL script that feeds OpenSees and loops through different values of permeability (k) for the same model. This model analysis consists of four stages, with the first stage being a gravity stage. Additionally, I have attempted to create an MPCO recorder using the specified format.

recorder mpco "C:/OpenSees-Solvers/B24F_LE_E2e8_k_${kperm}/B24F_LE_E2e8_k_${kperm}_recorders1.mpco" \
-N "displacement" "velocity" "acceleration" "reactionForce" "reactionForceIncludingInertia" "pressure" \
-E "force" "deformation" "localForce" "equivalentPlasticStrain" \
-E "strain" "stress" "tangent"

While attempting to create the recorders (before the gravity stage), I'm faced with this error: Could you please provide advice on how to resolve this error?

Best regards,
Ryan

This is strange. That error should never happen.

Can you print your kperm value? are you sure there is no white space in it?

Could you explain what you mean by "white space"?

Hi, I think STKO Team meant any spacing in the kperm string. For example, if your kperm is "Hi there", you can notice the space between Hi and there.
