Hi,

Could someone help me invert the direction of the load while using SFgrad?

I am trying to apply a triangular pressure on a surface (component called Nmon) but the applied load is in direction +Y, however i would like to invert the direction of the applied load to -Y. The load magnitude varies in the z direction.

I am using the SFgrad command, as follows:

SfGrad

SfGrad, Pres, 0, Z, 634, 1e4 !SfGrad, Lab=Pres, SlKCN=0, SlDir=Z, SlZer=ZAlb, Slope=1.e4 = 10 m/s^2 * 1000 kg/m3

               

AllSel, All, All

     

CmSel, S, NMon

NSel, R, Loc, Z, 500, 634 ! NSel, Type=R, Item=Loc, Comp=Z, Vmin, Vmax, Vinc, kAbs

       

Sf, All, Pres, 0. ! Sf, Nlist=All, Lab=Pres, Value=0., Value2, – , MeshFlag

Hi Alexandre,

Can you please check this help documentation on the "SFCONTROL" command and see if it helps?

Thanks,

Hi Alexandre 

Have you tried simply changing the sign of the load and slope?  Mike
