Transposition of load vector

Transposition of load vector

Transposition of load vector

(OP)
Hi

I want to perform the following multiplication in ANSYS 11.0 multiphysics:

{r}^T  *  {modeshape}   where {r}^T is the transposition of the loadvector

I've applied gravity loads to a model using the ACEL command. When i do a modal analysis, I'm capable of writing each modeshape into to a vector {modeshape} using ARRAY.
If i try to do the same for the loadvector, the gravity loads are not included. Only manually applied forces on DOFS are shown in the written loadvector.
However it is possible to write the loadvector including gravity loads to an output-file, and thereby construct {r}^T manually. This method would be too complicated with many DOFS.

Can Ansys construct the loadvector {r} including gravityloads?
Can it make the transpotiotion of {r} so that the following multiplication is possible?

{r}^T  *  {modeshape}


Thanks!
