This article provides a workaround to restarting an analysis in SOL106 with thermal loads and avoid the fatal error "USER FATAL MESSAGE 9155 (GETLOOP)"
There is a limitation in SOL106 when attempting to restart a solution that includes thermal loads. Specifically, if the initial or restart solution has thermal loads applied, the software may trigger a user fatal error, as seen below:
^^^ USER FATAL MESSAGE 9155 (GETLOOP)
^^^ PARAM, LOOPID, 20 DOES NOT CORRESPOND TO A VALID LOOP IDENTIFICATION NUMBER.
The workaround to this is to copy the thermal loads in both initial and restart solution files. Here are some scenarios involving a fixed beam with applied loads.
The initial solution has 2 subcases
The restart solution has subcase 3 with loads added, and no loads in subcase 1 and 2.
Scenario 1: Mechanical Load in Restart Analysis
Scenario 2: Additional Thermal Loads in Restart Analysis
Scenario 3: Combined Thermal and Mechanical Loads in Restart Analysis
