Ansys Problem

Submitted by furat on
Hi
I am
working on a model on Ansys for joining two dissimilar materials. I
chose the element type solid 70. The problem was appears after I glued
the two materials using the volume glue command, then while meshing the
the volumes an error message appears (invalid topology for mapped
brick mesh).
The question is how can I glue these two materials and mesh them with mapped meshing command without problems.
Thank you

Hi friends,

I want to pursue my education in applied mathematics as a PhD student. However, I do not have a research topic. In MSc period, I have done a project in applying the WKB method to solve an eigenvalue problem which arise in the buckling of cylindrical shell made of Varga. I took courses like continuum mechanics, perturbation methods, and numerical analysis.

Could you please help me to define a research project about applying the perturbation methods to solve some problems in solid mechanics.

Thank you very much

hi dear ,I try to modeling and analysing a coating material prototype by use of the Ansys Ls-Dyna, hence I use of the pin on the disc modeling and I choose pin as a rigid material.

For sub material I use of the sub metal with the coating material, but I don't know rotating pin on the disc which command of Edload is suitable, because how much I try, just I can stimulation translate only a small sector of pin on the disc. Could you help me please.

Hello dears,

 

I would like any body here to guide me how to solv this small mistake in ANSYS. this is when I do modal analysis of reinforced concrete plate the natural frequencies of the plates are shown blow.

 

mode   TIME/FREQ    LOAD STEP   SUBSTEP  CUMULATIVE

     1  0.0000             1         1         1

     2  0.0000             1         2         2

     3  0.0000             1         3         3

     4  0.0000             1         4         4

     5 0.49150E-04         1         5         5

     6 0.12931E-03         1         6         6

     7  138.32             1         7         7

     8  148.95             1         8         8

     9  318.44             1         9         9

    10  337.85             1        10        10

    11  405.90             1        11        11

    12  459.88             1        12        12

 

 the wrong thing is why the six first mode are shown here. the frequency from mode 7 138 to mode 12 are corect , but they should start from mode 1.

 

thank you in advance for your help in this matter.

Regards,
