Webb) Change the value of DRFCTR (the third parameter in *CONTROL_DYNAMIC_RELAXATION). While the default menu value for this parameter has been set at 0.999, it has been found that a slightly larger value can improve the speed. For a gravity loading analysis, DRFCTF=0.9999 is suggested. cinnfm facebook
