We're two aeronautical engineering students having our firsts experiences with ANSYS.

We'd like to transmit a force applied from a certain distance to our structure (made with the elemnt type SOLID95). In order to achieve this, we use the element type MPC184 as a rigid link. But the force is not transmitted in the solution.

We would really appreciate if someone could help us.

PD. We've developed the APDL code which follows this lines so as to try if we're able to achieve what we want with a simplified model.

Code:
PREP7
ANTYPE,STATIC
ET,1,MPC184 !RIGID LINK (DEFAULT)
!NLGEOM,ON
ET,2,SOLID95
KEYOPT,1,1,1
