[GiDlist] Iges units

Post by Mark Smith »

Hi GiD developers
I exported some geometry from GiD 11 and it automatically assumed that the units were metres instead of mm which I wanted so had to edit the iges file header. Maybe there should be an option in preferences-exchange where the units could be selected?
Regards
Mark

[GiDlist] Iges units

Post by escolano »

Hello Mark,



The problem is that GiD doen't has any unit for its geometry/mesh, but to
export in IGES this format require a unit name, not exist the option of
'unspecified model length units', and GiD is writing always the same unit
(probably meters as you said).



We want in future to handle a 'model length unit' in GiD, not only as an
special label to be printed in case of IGES export.

[GiDlist] Regarding loop over elements

Post by Deepak Samal »

Dear All,

I have to assign a set of elements each time to different materials. I have
around 60 different materials and around 9000 elements. Problem is
previously I was assigning elements by creating different layers for
different materials and assigning elements by using loop over elements by
setting the corresponding layer ON. But now I'm in a fix whether I should
be creating 60 different layers for 60 different materials and assigning
them the corresponding elements or is their any better way to do that?

Thank you

[GiDlist] Regarding loop over elements

Post by escolano »

I don't understand well your case.

Are you trying to calculate the same model several times changing every time
the kind of material?



you can create a Tcl procedure to automatize tasks. With Tcl-GiD commands
you can ask for the current model properties (layers, materials, entities,
etc) or you can change this propertities (assing materials or conditions ,
create entities, etc.)

This procedure could be set as a 'macro' to be invoked from an icon of the
'macro toolbar'



Are you using your own problemtype or a third part problemtype?

If you are developing your own problemtype maybe you can change your
approach, and instead a 'GiD material' could use a 'GiD condition' and
instead of define this condition as 'over body elements' and apply it to
each one of its elements could define the condition as 'over layer' or using
last GiD 11.1.x versions as 'over group' and then you can set once the
entities of the layer or group and to apply the condition (that represent
your material) it is necessary to select only a layer or group name.
