    dependent parameters

    I have three geometric parameters. a, b and c. i want to know where and how can i make parameter b dependent on c? for example that c must always be greater than b, if b[5...10] und c[4...20] a matrix was created by DesignXmodler. but errors were shown. is there an IF statement that can be...

    Optislang and DesignXplorer

    i am currently using optislang instead of DesignXplorer to do a parameter study. I am now encountering the problem that Optislang does not show all possible parameter combinations. is it because Optislang is designed for optimization and not for variation? My goal is not to optimize but to...

    determine convective thermal resistance in Steady State Thermal ANSYS

    i try to determine convective thermal resistance (Rconv) at different diameters of channels in Steady State Thermal ANSYS , but did not work so far. because if i define the channel as 3rd boundary condition (convection), i have to define the temperature and heat transfer coefficient h, what i...

    Define heat transfer coefficient as function

    Hello to all, i would like to define heat transfer coefficient as a function (in Steady state thermal), i.e. in relation to channel diameter, Reynolds number and Prandtl number. I can't define this as a constant value because the diameter is constantly changed by Design of experiement in Ansys...

    Boundary conditions for injection moulds

    Hi all, I would like to simulate a small cut of the injection mold (see picture), and first challenges are: what are the boundary conditions and what analysis system in Ansys (I simulated that in thermal stationary analysis) should simulate that. My boundary conditions are (see picture): on the...

    Master thesis suggestions

    Soon I will write my master thesis. I would like to deal with the topic FEM or your applications. Can someone suggest a topic that will be interesting in the market in the future? What about FEM in conjunction with Artifical Intellegence. Thank you

    Steel parallelepiped simulation

    Hello, I am currently working on the creation of steel parallelepipeds with a square cross-section in the unloaded state exactly into the cavity with ideally rigid walls and can slide against them with friction. since the walls are rigid, the displacements of steel blocks in X- and Z- direction...

    how can I calculate the stress in X- and Y-direction

    Hi all, A steel parallelepiped with a square cross-section fits exactly into the cavity. it's loaded from the top surface(see picture). how can I calculate the stress in X- and Y-direction if the strain in X- and Y-direction is zero. Thank you

    Create Joint by Python

    Hi, During my work I have to manually create over 100 joints in Ansys Workbench because I work on large machines. my question: is there any code (e.g. Python) that makes this strenuous work easier? [ponder] Thank you

    Joint Revolute or Fixed?

    Hi All, a shaft is driven by a motor, it is supported in two places by ball bearings and connected in third place by a motor. how can I use this example in Ansys WB? 1. variant : two places, where the bearing is mounted, as revolute (joint) and the third place as fixed joint. 2. variant ...

    real constants shell181

    Dear All, which real constants should I choose for a cylindrical shell? I have selected the shell181 element. I can't find in any books which real constants match shell181 element. Thank you
