Changing value of gravitational acceleration?

Hello!  I'm new to FEFLOW and am interested in modeling groundwater flow on Mars. Is it possible to change the value of gravitational acceleration to the Mars value to accurately model groundwater flow on another planet? 

Hi Sebastian, interesting question. You can change the direction of the gravity vector, but not the magnitude. I am wondering whether you could do a math trick by upscaling/downscaling other parameters in order to achieve your purposes. Cheers Carlos
