[Wien] Tetra-elastt error

Dear Users I am running tetra-elast for elastic constant calculation (for the given example PtSi). C11+c12, C33, Czz run quite well but for C11-C12, C44, C66 i face the following error. Please suggest the possible solution. .machine0 : processors running dstart in single mode DSTART - Error ** d

Thank you Prof. Blaha I followed the steps: 1. made case.struct 2. ./command_init_lapw 3. ./T_command_run_lapw USUALLY, TETRAGONAL SYMMETRY HAS INTERNAL COORDINATE AND YOU MUST RELAX YOUR COMPOUND. For calculation C11+C12 , C33, and Czz symmetry of tetragonal compound does n
