Variable Point Coordinates

CdricCd

Hi,

 

I try to make variable points coordinates using the VARVAL function but I always get 'Error Evaluating'.

I basically created a Solver Variable (Value : Lin = 1000) and then I use VARVAL expression in the point coordinates, which points on the .id of the solver variable but always the same message 'Error Evaluating'. It works on Forces but not on points. I know it's possible in Adams so I think it's possible with Altair !

 

Thanks !

Hello -

 

If you could elaborate on what exactly you are trying to achieve, that would help us suggest a more appropriate solution. May be like what is the scenario that you are trying to simulate.

Unlike force of type expression, point is a motionview specific entity and VARVAL is a solver function. Hence it cannot understand the function.

 

You can refer the solver variable's value into the point's coordinates by using the .value attribute as shown in the attached image. But note that changing the type of the variable from a linear value to a non-linear like curve or expression can break this reference.
