    linearized stress

    Review the Ansys help menu for Path operations. You can define a path through the wall of your pipe based on nodes and plot the linearized stresses along this path. Depending on how you define your path, Ansys will interpolate between the path points when plotting the linearized stresses and...

    superimposition of pressures

    Why not apply the pressure using the SF command instead of applying it to an area? All you would need to do is select the area that you currently apply a pressure to, select the nodes connected to that area (NSLA command), and apply your pressure using the SF command. If you don't want to go...

    superimposition of pressures

    Check the manual for information on the SFCUM command. This is a setting that controls if surface loads (such as pressure) are added or replaced when applied more than once. I believe the specific APDL you are looking for is: SFCUM,PRES,ADD,1,1 This option is also located in the GUI under...

    Automatic naming of components

    I don't have Ansys open at the moment to test it, but I think the command would be (using the variable name in your example): cm,areanodes%areanumbner%,node !Make component from nodes

    NFPA 69 Fy Stress Ratio

    Not sure about the Fy being specifically listed, but material properties for yield strength (Sy) and allowable strength (Sa) are given in Section II of the Code for a range of operating temperatures.

    New element type in ANSYS workbench 11

    The elements do not need to be exactly square for an accurate solution, as long as it is not a greatly skewed shape with one or 2 sides more than about 5 times longer or shorter than the other sides. Ansys will generally give you a warning or error message about element aspect ratio if that is...

    New element type in ANSYS workbench 11

    Under the mesh component in Simulation right click and insert a 'Method'. This can be set to hex dominant, which will convert most if not all elements to hex if the program is able. Depending on you're geometry you may also look into swept meshes or other options (check users manual). Let me...

    Stress change with mesh density.

    Are the large stress and drastic increase located at your fixed support? If so you could be getting a singularity effect from the constraints and no matter how much you refine the mesh the stress will incress infinitly. The mesh density does effect the final results. In general, a finer mesh...

    New Nukes?

    How to split the data? office 2003

    For LHS-RHS in column A: column B = REPLACE(A1,FIND("-",A1,1),10000,"") column C = REPLACE(A1,1,FIND("-",A1,1),"") This will put LHS in column B and RHS in column C. Should work as long as the first hyphen (left to right) is the hyphen seperating the 2 sides, and as long as the LHS is less than...

    Fluid-Structual Interface

    Hello All, I'm curently looking to undertake a CFX to Workbench FSI. The problem is that all I currently have is the CFX project. The cfd analysis was completed outside of the company and all I received were the CFX files (.cfx, .def, .gtm, .out, and .res). I don't have much experience with...

    UDF REFERENCES

    Was it a sketched counterbore hole? That might be the required 3rd reference, sketching plane. If it was just the default hole w/ counterbore feature then I am out of ideas

    convert microns cubed to picoliters mems application

    1 micron cubed = 0.001 picoliters 1 micron^3 * (10^-6 meters/1 micron)^3 * (1 liter/0.001 m^3) * (1 picoliter/10^-12 liter) Sound about right?
