GiD forum

Hi everybody, I have got a question about loads:
when I apply a load over a point, this load is constant in this point and then it will be transferred over a node, that´s right.
But if I want to aply a load non constant over a line or over a surface, for example a load which it depends on the x-variable along of the entity, this means the x-coordinate will be the x-coordinate of the node or the x-coordinate of the center of the element but not the x-coordinate along the line or surface. This is different to my idea because at the end the load is constant in that point and I don´t want that.
The problem is that I´m doing a problem type for Cosmos in 3D with solid elements and Cosmos don´t admit loads non constants, so I have to give them from GiD.
Could you tell me how I can create this condition?

Thank you, very much.

I wait your answers.

I don't understand well your question.

If you use a condition with a autocalculated #FUNC# field, you can use for this field a equation using the variables x,y,z and other field values.
This x,y,z are the global coordinates of each node or element center generated from the geometric entity (not the line or surface local parameter coordinates).

What you want exactly to write as input for COSMOS?

Hi, other time.
Perhaps I didn´t explain very well my question.
The problem is that x,y,z are the global coordinates of each node or element center generated.
My question was for example, if I apply a load over a surface I have two possibilities:
1.- When I do my conditions archive the load is transfered over his nodes
2.- The load is transfered over his elemens
In both cases, the final load is constant in the nodes or in the centre of the element.
But if the load wasn´t constant because it depended on the one variable.What can I do if I want that the final load depends
