Ansys Problem

Use the book "ANSYS 11 for Engieers" by Shaum Tickoo of Dream Tech Publication. you will find answer for Mapped Meshing and to ur problem also.

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,
