    A = B+C; if I want to get B depending on A?

    Nice answers! The idea is having only 3 cells I see one needs some programming to do so; I don't know about it my colleagues do. Thank you all regards,

    A = B+C; if I want to get B depending on A?

    Thank you for the fast answer. The "goal seek" is nice; I didn't know it; but it is not what I was looking for; it takes some time The nested IF idea could work, I have to check. Also making different scenarios with pulldown menus to choose in each case what we want to introduce.... The best...

    A = B+C; if I want to get B depending on A?

    Hi there, I tried to be specific with the subject but I don't know if I succeeded. In excel, I have a formula (output, A) in one cell which is the addiction of other two (inputs B and C) But, If I want to introduce a value in the formula (A) and I want to get the value of B with the same...

    Create different bodies with Design Modeller

    Hi there, I add the surface as frozen (and not add material) and it works thank you!

    Create different bodies with Design Modeller

    Hi there, I want to create a simple geometry with the Design Modeller for an axisymmetric analysis. I create different sketches, then surfaces from each sketch. The problem is in the end I only get one body (and one part), so I can't give different properties to each surface. Does anyone...

    Concrete modal simulation

    Hi there, I was asked to make a simulation of a reinforced concrete block (16x10 m2)in 3 thickness: 1.0 m 1.5 m and 2.0 m in order to choose the optimum value This turned out to be more complicated than I expected. I made some assumptions. The first one the concrete is isotropic in all the...

    Force calculation of sphere against plane

    Hi there, I contacted the author of the paper and he agreed there are mistakes. I have a 50 mm Radius feet (10.9 quality) against a 16MnCr5 plate The point is I can't say how much weight we place, but what's the maximum one cheers,

    Force calculation of sphere against plane

    ;-) we want to know if we can put more weight on it; much more

    Force calculation of sphere against plane

    Hi, This system is already manufactured and working. I didn't realise the materials we were using For the plane (plate) is 16MnCr5 which has a minimum tensile strength of 1000MPa For the sphere (screw) the quality is 10.9 so 940 MPa I'll do the calculations, but I'd like to ask someone to...

    Force calculation of sphere against plane

    Hi everyone, Thanks for the answers - The xcalcs page is very cool. I made some analysis and I got the following results: Average compressive stress: 1340 MPa Maximum compressive stress: 2010 MPa The contact is steel against steel. Supposing a yield strength of 200 MPa I'm out of the 3-4...

    Force calculation of sphere against plane

    Hi ztengguy, Yes, I'll check the statics. and each component. This is not the problem What I need to know is what happens in between these two parts (spherical and planar) Cheers,

    Force calculation of sphere against plane

    Hi there! I need to check the maximum weight we can put on a platform we have. There are different parts between this platform and the floor. It doesn't seem difficult to check each part, but the platform is place on the top of three feet like the one in the attached picture: a sphere touching...

    Reinforced concrete simulation

    Hi everyone, I have to perform a vibrational simulation of a 16x10m2 block in order to compare different thickness: 1 - 1.5 - 2 meters This doesn't seem very challenging except for the point the block is made out of reinforced concrete. I've never done a simulation with concrete; I tried some...

    Material with low friction coefficient against PVC

    Thank you! I asked a friend working in a chemical company if she can get me some I will also try with plastic trash bags cheers,

    Symmetry with the workbench

    Hi there, I might understand it wrong, but I see it completely symmetric in both geometry and load. Actually I decided to cut into two in order to make it easier. Attached a drawing of a sketch (sorry, i don't have ansys access right now). Let's think about a rectangle. Heat flux at the...

    Symmetry with the workbench

    Hi there, I'm trying to run a simulation in the workbench; it's a 2D thermal simulation. Since it is symmetric I only designed half of it. In the mechanical I insert the symmetric region. It is a line. and the symmetric normal (an axis) I have problems with the results. They are the same...

    2D Analysis with Workbench 13

    I already found it. right click properties and a new panel pops up. cheers,

    2D Analysis with Workbench 13

    Hi everyone! I have a problem to be solved with long sheets and rubbers. They all have the same length so I think it is better doing a 2D simulations. I'm using Ansys Workbench in the version 13. In the version 11, the one I used to learn Ansys, there was an option in the project window to...

    Material with low friction coefficient against PVC

    ahá, I didn't know the official name. I think I will also try with trash plastic bags (the typical black) and the ones for recycling plastic (yellow ones) Cheers, david
