Assign coordinate system

Hello,

In the model I am working to, grids are referenced to a local coordinate system, which is previously defined.

Is it possible to assign the global system to the grid reference?

If I go to Analysis>System>Assign I cannot find how to select the global system.

Thank you very much for your help

uhm, there should be an 'unassign' button to do that

you can select the nodes then enter below command:

*systemsetreference nodes 2 0; # 0 is id of global (basic) system

If the local system is useless, Delete it simple /emoticons/default_smile.png' srcset='/emoticons/smile@2x.png 2x' title=':)' width='20'>
