hi
i want calculate the acceleration of some points in our ship and we simulate the ship motion in wave( ansys cfx 15). its impossible to calculate acceleration?

Are you doing this with a rigid body model? If so you can get the accelerations of the body using the rbstate variable.

hi
yes i am using rigid body. now ?

.... so you can get accelerations from the rbstate variable. So your question is answered, isn't it?

when i write the rbstate the ansys say unrecognized rbstate.

Read the CFX reference manual for information about when you can call it and the syntax you need to use.
