Impact/impulse force

forestis

I want a force to act on a body just for short period of time , to be like an impulse.

Could i just apply a static force to act for 0.1 seconds?

Hi forestis - You could use the type 'Expression' and have an expression something like this - `STEP(TIME, 1,0,1.1,100)+STEP(TIME,1.1,0,1.2,-100)`

In this expression, the first STEP function increases the force to 100 from time 1 sec. until then it is 0. In the next STEP function,  the force is being dropped down back to 0.0. (otherwise the force will remain at 100 for the remaining time of the simulation)

 

You may also use a Curve that has the impulse profile of your choice and use TIME as the independent variable while using the type Curve.
