    Problem seeing results in Paraview,OpenFOAM

    Hi, I did a simulating in OpenFOAM 6 and can solve it. However, when I open paraview to see the results, I can only see the velocity U. I tried to see the kinematic pressure p, but I can't see any result there. Any ideas on what I might be doing wrong? Best regards,

    raw data for S-N curve of steels

    Dear fellow researchers, I would like to know where I can find the editable/raw data for a set of points of a S-N curve for a high strenght steel, like a dual phase. I can only find the S-N curves, already built, not the data that originated the curves. I thank you in advance, Best regards...

    How to change element type in ANSYS Workbench 2023 R1

    Dear fellow engineers, I am using ANSYS workbench 2023 R1 for a static analysis. However, I can't select the element type. I can see in the solver output that currently, SOLID187 is assigned. However, I am modelling a structure similar to a construction brick and wonder if shell elements, like...

    components for electromechanically actuated robotic gripper.

    thank you for your reply. No, I do not have experience, that's why I need to know the components I need, so I can select them and order them. In either case, which components are needed, to have a fully functional system? Thank you!

    components for electromechanically actuated robotic gripper.

    hi, Answering your questions: I want to build a prototype" The answers to your main question will be found in your answer to this one: Why? Why are you building a prototype instead of a real gripper? What is it that you don't know? What are you trying to learn from the prototype? Be specific...

    components for electromechanically actuated robotic gripper.

    The gripper is made of steel, to be actuated with a clampling motion (and force). If I want to build a prototype, which components do I need to create and control the motion of the fingers?. This is a two-finger gripper. Best regards,

    components for electromechanically actuated robotic gripper.

    Hi, I need to print a gripper by FDM (3D printing). the problem is that we need components for the electromechanical actuation system. -We are thinking of using a servo motor, its control unit. -There is also a pressing cylinder, in which we are thinking of using a pneumatic cylinder...

    differences between 3D printing a part in metal and in polymer

    Hi, I need to print a part by FDM (3D printing). The problem is that, where I work, we can only do it in polymers, like PLA. What are the practical considerations that are important for polymers that are not for metals, in terms of processing conditions and the expected material properties? I...
