Hi flash3780, thanks for your reply. Yes this is the direction I am looking for. However if I understood the CBDOF command properly. It interpolates the output of the ANSYS analysis and and provides solution at specified node location.
In my case I have not started the analysis yet. I have...
Please let me know if I am thinking in the right direction. I can define the locations at which velocity was recorded as keypoints. Provide I can calculate appropriate forces at these points using Morison equation, I can easily transfer these loads to structural node locations.
Force...
Hi,
I am trying to setup an analysis where the velocities have been recorded in a fluid medium at particular locations. Now I have to use Morison equation to calculate the force at those particular locations.
The structure under analysis is to be applied with forces generated by the Morison...
Hi folks,
I am a newbie in using VB family of languages. I wrote a .NET dll which creates a process (objProcess.Start()) in one function and returns the pid and then in second function I pass the pid and monitor it using objProcess.WaitForExit(). I exposed it to the COM and registered it using...
Hi,
I am trying to generate an impulse response of a simply supported beam, with a spring element at the end. A very crude picture of the problem is shown below. The - part is the beam and /\ part is the spring. The impulse force is applied at the middle, in vertical downward direction...
Hi,
I am trying this simple example of a cantilever beam. I want to obtain the impulse response of the structure and have the following APDL script. I should get a harmonic response, what I get is a ramp.
I will appreciate if someone can point to my mistake...
I was trying to read and write the HB formatted file through GUI. I realized that in command line form HBMAT file has a mapping parameter, which when set to YES writes a .mapping file which has a list of global DOF corresponding to the global matrix.

Hi all,
I used HBMAT command to obtain the stiffness and the mass matrix.
I also have the modeshape vectors (which are in ascending order of node number, obtained them using *vget) for the same problem.
My aim is to rearrange the modeshape vector in the same fashion as the system matrices are...

Hello Everyone,
I am having a weird problem, and I am pretty sure I have some wrong understanding. In this problem I have a rectangular beam, which is to be subjected to convection and radiation boundary condition in Thermal physics and then to stress analysis in Strucutral physics.
I have...
What I resolved to, is a workaround using:
variable = exp(0.78*log(A))
So for now The problem is resolve. But if you know of any direct command, I will definitely like to know.

Hello everyone,
I am trying to write some variable = A^0.78 i.e A to the power 0.78. But the script aborts with error msg:
Unknown expression in input line.
Can anyone help me with writing this correctly? I am going through the manual but is not able to locate it yet.
Regards
Hi all,
I think I found what I was looking for. I realized that .page file is created when ansys is launched so I specified the work directory in the launcher and now .page file is created at the specified location.
Thanks
Hello Everyone,
I have a windows partition which is around 25GB most of it is full and I want that the page file which is being created by ANSYS goes to an external hard drive. So I changed the working directory to a directory on external drive. Files except the .err, .lock, .page and...
With some valuable advise from this forum I have been able to offset the shell element and place it on a solid thermal element using.

Hi Guys,
Thank you for your comments. I was having some hardware problem so could not try out your suggestions earlier.
I appreciate cbrn comments, Its good to confirm this. I checked compatibility between the the shell181 and solid95 element and it seems to work fine.
Actually I was...
