in my project,actuator's output is force.so,i can't use force as input souce for FEM based linear actuator.

I'm uncertain since no examples have been provided. However, one possibility is that the input to the actuator is a Commanded Force signal, which is sent from the Controller software.

Hi, can you point out the examples you are referring to? Most of our highest fidelity examples, including FEM based blocks, don't have force as an input. You setup a supply circuit, connect a motor model, and the only time you have force is when you are "mimicking" the load by suppliying a constant force as the load. Is this what you are referring to? This is what happens in real life as well in testbenches, where the load is a set force (or torque).
You can as well replace the load from a constant source with a model of your mechanisms to be more realistic.
Like in this example, where the load is a mass, and the force is read, not given as an input:
