Variable Forces in Relation to Mass/Variables

Turbokraken

Hi All,

 

I have a modelling question regarding Forces.

I would like to assign a force magnitude based on an equation. There is a neat option available within the Forces window itself, but I need to incorporate some variables from my model, e.g. the mass of the model. (I am not trying to model acceleration forces, so GRAV card is not an option here).

The question is how can I incorporate a changing force into my optimization model?

I will need to declare variables somehow, of course. Which type of variable can be used within this equation? Can I simply pop in a 'response'-name like I can with dequations?

 

Any advice would be fantastic.

 

Best Regards,

Lennart
