      It took me a while to run a large Ansys model (3 pieces pieces, attached like A-B-C). Model has close to 2 million elements My frequency responses are as followsnNODAL DIAMETERS (ND)nND4nND4nND5nND5nND3nND4nND3nND6nND2nND6nND6nND7nND7nND8nND8nI always thought they should occur in sequential order so i am baffled with results. nI am using program controlled solver. AM i doing something wrong?n
