Field function

rasoole · December 21, 2016, 06:25

hello

i want to write a user defined field function for ( y/v*t ). so i write
($$Centroid[1])/($${Velocity}*$Time) for defined field function but an error.

Could anyone tell me how to define this equation profile by using field function?

Thank you!

There is a scalar/velocity type mismatch in your function. A direction needs to be defined for your velocity.

You also should take care of a zero velocity or time leading to a zero denominator.
