Hi,
When I run gap tow analysis for transportation analysis and SACS programe then it have error as per: ERROR GRAV IS AN ILLEGAL LOAD CASE SELECTION
please help me with not that i set up for run is below:at Gap elements -> Number of Iterations: 600-> Convergence Tolearace: 0.00001
and on sacinp.model : LCSEL GP GRAV
Hi Aisyah,
LCSEL in your model file should read load combination, not load condition. You may want to check whether you have input a correct load and select a correct load combination to be read by SACS. I hope this helps.
