Hello Everyone,<\/p>\n

I do a lot of modal analysis of an impeller. <\/p>\n

I use the following commands<\/p>\n

ANTYPE,MODAL<\/p>\n

MXPAND,nmodes (nmodes=500)<\/p>\n

PSTRES,ON<\/p>\n

MODOPT,LANB,nmodes,0,2000<\/p>\n

Using the above commands the maximum load step the solver goes is 9. Is there any particular reason it is fixed till 9 even if I changes nmodes=250 only the substeps changes and not the load steps. The same I see in ANSYS Workbench. I can changes the number of modes but the loadsteps still is limited to maximum 9. Can someone tell me where or what can is needed to change this maximum lpadstep value ?<\/p>\n

thanks in advance.<\/p>\n
