    Mapping forces defined at coarse mesh to fine structural mesh

    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...

    Mapping forces defined at coarse mesh to fine structural mesh

    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...

    Mapping forces defined at coarse mesh to fine structural mesh

    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...

    VBA calling VBS gives "ActiveX component cant create object"

    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...

    Numerical damping effect

    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...

    Impulse respose using transient analysis

    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...

    Extracting global DOF list

    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. HN

    Node & DOF list corresponding to Mass & Stiffness 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...

    Extra element type definition changes the problem

    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...

    Putting A^0.78 in APDL

    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. Regards Harsh

    Putting A^0.78 in APDL

    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

    File.page directory location

    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

    File.page directory location

    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...

    Aligning SHELL element over a SOLID element

    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...
