[ GiDlist ] GID crash with iso surfaces

[Ruben O. Domenech]

HI all

I'm new to GID and am trying to walk every tutorial. I passed ok the two ones on meshing and pre-processing, and follow the post-processing up to the point of trying to generate iso-surfaces (in both exact and automatic modes), when the program invariably crashes. I'm selecting the option from the "VIew Results" menu, and all the remaining options seem to work ok.

I have installed ver 6.1.2 with the one month optional psw, and Calsef 5.5 also with the temporary allowance.

Below are samples of the error messages obtained.

Any help welcomed. Regards,

hello again;
anybody can explain to me or send me a tutorial to CREATE CONTACT betwen
volumes, i consulted the help, but i did not understand very well.
i suppose, when there is a contact between two bodies, i select surface
in contact (these are in the same plane), and then when i mesh GID
creates elements gaps, but i did not get it.
when i select the surfaces Gid say me "0 new contacts"
a lot of thanks
Pablo

To create a volume contact, the user must select two equal surfaces, physically located at the same position.
(or using Separated volume, can be separated by a displacement/rotation)

Then these two surfaces are meshed with a one-to-one relationship between nodes, and are created degenerated contact elements connecting the nodes. (if it is possible more than one transformation between surfaces, the user is
asked to select pairs of analogous points).


In conclusion, the creation of contact-surfaces or volumes can be considered like a mesh generation option of GiD.

If your program cannot require this one-to-one relation of nodes, you can use a condition to mark the contact nodes or elements.

Best regards
