    Model Conduction as Convection

    I am sorry, I meant the CP commands, not the CYCLIC command.

    Model Conduction as Convection

    I finally got to make the cyclic symmerty in APDL with the CYCLIC command but unfortunately this is not suitable for me because my loads are not symmetric. The thing I am trying now is the one I asked in the first comment. I am trying to model the conduction to the rest of the piece as a...

    Model Conduction as Convection

    Hello again. I have also made a simple model in ansys but I have recieved this two error messages. I am using the Academic version of the ANSYS Mechanical APDL 17.2. This is the one I have available and maybe this is the problema, that the transien termal analysis is not available in this...

    Model Conduction as Convection

    Okey, thanks for the clarification. I will try to do it in my model. Anyway i just want to explain myself by saying that i saw that statement in an ANSYS guide, specifically the ANSYS Mechanical APDL Advanced Analysis Guide. I hope I will be able to do it in APDL. Thanks again for the interest!

    Model Conduction as Convection

    Thank you both for your answers, I will answer you in order. A symmerty boundary condition would be great. As far a as I know it means that in the elements where you define this symmetry boundary condition ANSYS will supose the same conditions un both sides of the symmetry boundary in every...

    Model Conduction as Convection

    Hello, I am having trouble with the meshing of a model to which I want to apply a thermal load and make a transient analysis. I thought of simulating only one part of the whole model adding a convection boundary condition in the edges that will act as a substitute of the material that I have not...

    Hexaedral element mesh refinement

    Hello, I am working on a termal 3D model and I have just Meshed the model. I would need to refine the mesh in one surface but since I am using hexaedral elements i can't use the XREFINE options. ANSYS wont allow me to do local refinement. I am OK with the size of the rest of the elements but I...

    NO conduction between elements in a body

    I think i found the problema. I have done the VMESH after the VGLUE and it worked, i got to extend the heat along more elements tan the ones in the first line. I have to check the units too but i think the main problema was this i just wrote. In the script avobe the VGLUE function was not...

    NO conduction between elements in a body

    Hello again. I have created a simpler model to see if i made any mistakes in the way and the result is the same. As yuou can see the temperatura stays at 20ºC once you have passed the first layer of elements. I will put two pictures of the model since i dont know how to plot the nodal...

    NO conduction between elements in a body

    Hello, I am working with Mechanical APDL, I have built a body, meshed it and filled the volume with solid70 elements. I have defined thermal loads and calculated a transient analysis where the heat source moves along the workpiece. The problem is that it seems that olnly the first layer of...

    How to rotate a local CS

    Hello, i am new in the forum and this is my first post. Also new ANSYS user. Here is my question. I am working in a simulation where i need to move the heat source around the workpiece. I have created the solid in the global coordinate system and i have created a local coordinate system to...
