    Saving a specific value as a function of time to file

    Hello, I am doing transient thermal electrical analysis. It is working fine and I can plot the temperature in a given node as a function of time in Ansys. But since I will be doing the same thing with many different structures I would prefer to automate the process and write the temperature...

    Finding flux through an area

    I am doing 3D thermal-electric analysis. I use constant voltage and constant temperature boundary conditions. I want to find the total current flux through an area (the total current). How can I do this? Best regards, siggi84

    Results to datafile

    Hello, I have one problem with ansys. What is the easiest way to write ansys results (i.e. temperature and electric field) to a datafile. I want to select all the nodes adjacent to a line (using the NSLL command) and write out their position, temperature and electric field in a separate file...

    Divergence because of temperature dependent material properties

    I have solved the problem. The trick was to enable line search: SOLCONTROL,ON LNSRCH,ON best regards, Siggi84

    Divergence because of temperature dependent material properties

    I am having a problem with temperature dependent material properties. I am doing thermal-electric analysis in 3D and I am using the solid69 element. The structure is made of silicon, silicon dioxide and platinum. On top of a thin silicon dioxide layer I have a nanowire which is heated...

    Divergence

    Thank you. I actually found one error in my code, but I also had to increase the number of nodes in the SiO2 layer. Best regards, Siggi84

    Divergence

    Hi, I am using Ansys to calculate temperature distributions in nanostructures. I am doing thermal-electric analysis in 3D and I am using the solid69 element. The structure is made of silicon, silicon dioxide and platinum. On top of a thin silicon dioxide layer I have a nanowire which is heated...

    Ansys: Thin layers

    I am having a problem with thin layers in ansys. Simply speaking I have a Pt nanowire (8 um length, 1 um width and 0.05 um thick) on top of a thin layer (100 um length, 100 um width and 0.1 um thick) of SiO2. The SiO2 layer is on top of a very thick layer of Si (100 um length, 100 um width and...

    Mapped meshing: Two adjacent volumes with overlapping areas

    Thank you slumdogengineer, I had already realized that I could chop the volume into pieces, sharing areas (and lines). But I didn't realize I could define the mesh sizing such that the elements coincide. By combing those two methods it seems like I can mesh my geometry. Best regards...

    Mapped meshing: Two adjacent volumes with overlapping areas

    Hello, I am having a problem with 3d mapped meshing. How can I mesh two adjacent volumes with mapped meshing if the adjacent areas overlap, but are not identical? If the adjacent areas are identical this is straight forward, you just mesh one of the volumes, then the other and finally use...
