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...

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...

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...

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...

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...

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...

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...

Hi there, I've been looking for the proper subforum for a while, I finally chose this one. We have a bunch of cables which moves back and forth around a 250 mm diameter PVC tube. We built the setup and when moving there was much vibration due to the friction between the cables and the PVC...

Hi there! I've been making a simple simulation of an aluminium plate. In a previous post I already asked how to get the reactions on the supports. My problem now is the more I refine the mesh, the higher the stresses get. This happens in a very specific area. I mean. Everything is "blue" and...

Hi all! I have an aluminium plate with some non homogeneity weight on the top. Under it, there are 4 legs sustaining it. I can get stresses and deformations easily (imprinting surfaces, applying forces, fixations...). But what i would like to know is the force in the reactions. I have a limit...

Hi all! I have an aluminium plate with some non homogeneity weight on the top. Under it, there are 4 legs sustaining it. I can get stresses and deformations easily (sewing surfaces, applying forces, clamps...). But what i would like to know is the force in the reaccions. I have a limit of...

thread560-259421 I found this post by chance http://www.eng-tips.com/viewthread.cfm?qid=259421&page=15 I can't further comment in it, that's why i'm starting a new one. My question is why is there the red lighting bolt in the part, when the external references have the green square. Thank...

Hi everyone! I'm working on a design of a small stand for some parts. This consists basically in a lower and upper support. They are connected with 3 screws. Adjusting them we can control the height and inclination (we want the upper part perfectly horizontal, so they all must stay the same)...

Hi everybody! I'm designing some unions with screws. Let's say I have to put together two sheets. The screw goes from the top and the lower sheet has the thread. If I'm using e.g. an M5 screw; what should be the diameter of the hole of the top sheet? 5 mm?? a bit more? I got some accurate...

Hi everyone! I'm in charge of the design of some platforms supporting some items. They will be made in aluminium (in order to make it lighter). On the platforms we have some (accurately placed) rails, many screws, some positioning pins and not really much weight I would like to ask you which...

Hi there! Here I bring an easy one, but I'm a beginner. I'm connecting several parts to a sheet with screws. The screws are ISO 4762 M8x25; the supported parts thickness is 11.6 mm. I need to specify the depth of both holes and thread in the sheet. A V-Bottom will be included (120º). In...

Hi there! I'm in charge of the design of an assembly. We have to position some little parts very accurately; in these parts there are 3 holes: two M6 screws and one D12 hole for a pin for positioning. The hole is D12H7 and it has a depth of 7 mm. I have to check the pin and the hole on the...

Hi all, Here i bring a simple question for Ansys workbench users. I use Ansys for structural and thermal simulations. I'd like to learn how to do magnetic ones. Here I explain the case i'd like to learn: I have a box made of mumetall (material with high magnetic permeability) to shield some...

Hi all! Here I bring a question: We are working on some special supporting parts which will hold a plate at low temperature. They have to be strong enough due to the weight of the supported pieces and also it has to allow the deformation caused by the shrinking of the plate Our first...

Hi everyone. Here is a very easy one, but after several years without studying theory of statics mechanics I got lost. Let's think about a neon sign. It is fixed with a horizontal bar. I want to study this bar. Attached a sketch to show this. The upper case, one bar; There is the weight of...
