Hello, I am trying to model a beam with distributed loading (triangular) in Abaqus. I figured out how to create pressure loading (N/m^2) or line loading (N/m) on a surface of the beam. But I did not find any option in Abaqus to assign any distributed moment along a line (Nm/m=N). Abaqus has...

Dear members, I am trying to find out the force per unit length of a helicopter blade while in hovering. I know from blade element theory how to calculate the lift force (1/2*rho*v^2*....)generated by one blade. For example, if i have 4 blades, then, the total lift force=weight of the...

Hello everybody, I am trying to model a helicopter blade with a twist angle if -12 degree. To understand the features of the twisted blade, I was searching on the internet and I have found that (in faa.gov)the blade twist angles are made in such that at the root the angle is greater and as one...

Dear friends, I am modeling a composite beam with layered airfoil like shells wrapped over one another and need to find the cross sectional properties. I know the equations of the airfoil curves but could not implement the theory to calculate the bending stiffness. I studies a lot but did not...

Dear all, Thanks for all your responses. Let me tell all of you my situation. For assigning the cross section, Abaqus only shows some built in geometry like rectangular, circular, trapezoidal etc. The attached file will show you how my cross section looks like.I don't know how to assign it to...

Dear Corus, Thanks for your reply. I have already assigned the material properties before running it. When I assign the whole section (by dragging), only part of it was green and most of the part was yellow. Then I changed the green ones yellow also by clicking on them. However, that model was...

Hi friends, I am working with abaqus in GUI for two years for modeling heat transfer analysis and I am switched to structural mechanics now. I need to model a closed central cross section (like helicopter blade) which has offset composite layers wrapped over it (2-3 times). Can anybody tell me...

Hi everybody, I have to run an fluid structure interaction model for almost 30s but after 1 second, the computer becomes hanged and after some time everything shuts down showing that your computer does not have enough memory. I use workstation with 32 GB ram. I have tried to run this a lot of...

Thanks both of you. I think these are the only possible ways. Pratik

Hi Danstro, Thanks for your reply. I know this, but the problem is, after I have completed running it for more than one day, without partitioning, I remember this. So I asked if any body has some alternative. What I tried to do then is to apply view cut and tried to find some node inside. But...

Hello everybody, I am trying to make convergence studies for my model and I have to calculate stress at a particular location for different mesh to make sure that the stress is not changing anymore with more and more finer meshes. But, as I change the mesh, the location of that point is also...

Hi DanStro, Sorry to reply you late. I was out side of my university for a couple of days. I tried recently by annotations to make this happen, but I think it should have some specific guidelines. Can you just give me the steps how I can do this? Thanks for responding. Regards, Pratik

Hello respected Abaqus users, I want to save a pic of deformed or undeformed stresses or mesh with three particular node on the model with their labels visible. Can any one tell me how to do it? I went to the options, common tab in the visualization module and turn on "show node label" option...

Hello dhengr, At first I thought so, but I could not find something like that. I am still trying. Pratik

Hello Steve, Let me see what I can do. Thanks for your reply. I reduced the number of outputs so that it can save some memory, but it is not working still. Even I have reduced the mesh size a lot. But no result. Pratik
