[GiDlist] problem_type_name.uni

[Wenshui Gan]

Hi,

What is the purpose of the problem_type_name.uni file? Does GiD use it to
convert units? For example, if the user enters a thickness in cm but my
solver uses meter for thickness, can GiD convert the thickness to meter? I
tried but it didn't work.

Thanks.

Hi, GiD is distributed with a .uni file (now incomplete) where
magnitudes and units are defined. If for some reason your problme type
needs one units not specified in the GiD unit file the you can provide
your own file that will complete the one provided in GiD.

GiD can make conversions of units when writing the properties to the
data file before the calculation start, but you have to mark the
properties as being of type UNIT, for instances

QUESTION: thickness#UNITS#
VALUE: 2cm

then in the menu Data-Data Units you can specify the output unit for
every magnitud, in your example
you have to provide LENGTH=m

after that all properties having a unit of LENGTH will be written in meter.

You an find more in the GiD help.

Now we are completing the GiD unit file.

best regards,

Jorge

Thanks. It did work with GiD7.4.3b. Previously I tried it with 7.3b and
it didn't work.

Hi,

I would like to know how I can create an elipse in Gid. Is it possible
to make it directly or do I have to make a bas file?

Thanks in advance.

You can create a circle, and then scale it (Utilities-Move) with the
appropiate scale factor in each direction.
This result in a mathematically exact ellipse.

Hi,
I would like to know that Gid makes an optimization while giving the node
and element numbers (such as the numbers are given in order or arbitrary in
the structure) and mesh tying (Combination of fine and core mesh in one
structure) is possible in GID.

Thanks.

GiD automatically renumber the nodes after the mesh generation, in order to
decrease the bandwith (maximum nodes diference between two nodes connected
by an element). This can be util for some direct solvers.

Can set the GiD variable "RenumberMethod " (utilities variables
renumbermethod, in the rigth hidden buttons) to
0 : for a GiD standard fast renumeration
or to
1 : to use a "Reverse Cuthill-McKee" renumbering algorithm.

About the combination of fine and coarse mesh, can assign different mesh
sizes to each geometric entity
(menu Meshing-Assign unstruct. sizes)

I am just interesting in the mesh tying feature of GID. I think this is
different from the unstructure mesh generation. At the attachment I sent you a
mesh structure which I want to generate.

Thanks

Using the copy/move tool, you can easy create the geometric surfaces as the final desired elements,
and then generate only a quadrilateral by surface.
(meshing-structured-Surfaces, num divisions=1 for all lines)

I attach a GiD file similar to your picture.



Note: must avoid to collapse the model, to not divide and share the lines between the big and small quads.
(your mesh is not conform)
