| void assemble | ( | long | lcid, | |
| double * | rhs, | |||
| double * | flv, | |||
| double | scale | |||
| ) |
Function assembles vector of right hand side. It is created by prescribed displacements, forces, moments, eigenstrains, etc. In case that the flv is not NULL, vector of load caused by forces only is stored in flv.
| lcid | - load case id | |
| rhs | - pointer to the right hand side | |
| flv | - array of load vector caused by forces only (default value is NULL) | |
| scale | - scale factor, it is used for subload cases |
