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...
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...
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...
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 Everybody,
I am runiing an fsi model for 40 seconds, but after some times running like 0.2 seconds for both solid and fluid, it hangs, and if I continue this way after 8-9 hours every window vanished showing that "your computer is low on memory".
Recently I have found that when before...
Hi everybody,
While running a cosimulation in abaqus, after sometime the computer hangs and after sometime(may be 10-12 hours) the program terminates and everything vanishes, but with a notice showing that "your computer is low on memory, and there are two options restart or close". When I...
Hi everybody,
I have to run the thermal stress analysis due to very quick heat transfer. I completed the heat transfer step by using an fsi model cooling from a very high temerature to room temperature. Now i want to give the temperature time profile as input load from the heat transfer step...
Hi everybody,
I am a new member here joined today and would like to seek your help for my research.
I need to model a quenching work to find some values similar to a resarch paper. But I dont now how to use abaqus very efficiently. Can any of you help me how to model the quenching work? I...
