谁用ANSYS建立过系杆拱桥模型?请指教
我在做系杆拱桥的计算,总说有错误代码如下:/COM,ANSYS RELEASE 10.0 UP20050718 17:49:23 12/05/2007 *** WARNING *** CP = 101.797 TIME= 17:54:00 Real constant 1018 referenced by at least element types 5 and 1. *** WARNING *** CP = 101.906 TIME= 17:54:03 The program chosen initial timestep/load-factor is arbitrary. It is necessary for the user to supply a suitable initial timestep/load-factor through the NSUB or DELTIM command for convergence and overall efficiency.
