Hi,

another question, can GID create a load vector, i.e. in the *.cnd file I
define a load condition as follows:

...
condtype: over lines
condmeshtype: over nodes
question: x1
value: 1.0 kN/m
question: x2
value: 0.0 kN/m
...

then I assign to one boundary line (l = 1m) of a rectangle this line
load . Does each of this 5 node of the boundary line after meshing get
0.25 kN(inner nodes) / 0.125 (outer nodes)? Or simply 1.0 kN/m? It seem
to be the last one.

yes you can,

The way I used to define the force vector is as follow:

in the .cdn file you can add a condition of point-load or face-load
as you mentioned above with whatever default value you wish.
I did not try to add units in there.

usually when I am writing or modifying the configuration files, I used to
look at one of the example files provided. You can do the same if you
wish.

For structural analysis, it could be very useful to take a look to the
configuration files of calsef (www.cimne.upc.es/calsef), the GiD+ module for
this kind of simulations.

Hello,

It is possible to define condition values that change depending on the x,y
and z coordinates. It would be the typical case for applying a triangular or
parabolic load to a boundary of the model.

To do so, check the type of field #FUNC# in the problem type conditions
help.

About the planar surfaces, they are being completely substituted by the
NURBS surfaces. It is better to use these.

Best regards,
