  Which software better for Finite Method Analysis?

  I have two options of software: ANSYS and Abaqus. I want to learn FEM but I am not able to choose the software. Please help me with reason and your experience.

  How to apply Neuman boundary condition to Finite-Element-Method problems? the problem it´s about heat transfer in one fin.

  I have the boundary conditions in a fin but I don´t know how apply the neumann condition (k*dT/dx when x=L it´s 0)

  How is it possible to add time effect to stress & displacement analysis using FEM?

  In many dental studies, the analysis of stress, strain, and displacement of tisues under applied forces shows the immidiate (momentary) effect of the force application, but they lack the ealuation ofIn many dental studies, the analysis of stress, strain, and displacement of tisues under applied forces shows the immidiate (momentary) effect of the force application, but they lack the ealuation of the time effect. Usually forces fade by time, & also some biological responces occurs (compression leads to bone resorption, while tension leads to deposition). Also, sutures (lines between ones of the skull ) can be opened under forces applied for some duration. Is there a way to simulate te effect of time in such cases?????

    The theory has been well established. You know even for metal such as tin, there is time-dependent deformation like creep and there are many mathematical description for that time-dependent behavior.The theory has been well established. You know even for metal such as tin, there is time-dependent deformation like creep and there are many mathematical description for that time-dependent behavior. You can find numerous papers on that subject if you search for example "visco-plastic" in the Web of Knowledge.

    Jan I also support your views. Numerical tools are just a way to validate the model but experimentally one has to ensure what exactly he/she wants to model. Same problem can be dealt with both LEFMJan I also support your views. Numerical tools are just a way to validate the model but experimentally one has to ensure what exactly he/she wants to model. Same problem can be dealt with both LEFM and NLEFM depending on requirements. And there are problems where simple damage criteria often solve the purpose. So detail the problem first then all members can give a very focused view rather than beating around the bush......

  3D analysis of a laminated plate using FEM

  thanks everybody actually i was a PG student doing my research work on 3D analysis of a laminated plate using FEM in the process got a doubt whether an analysis has to be carried out separately forthanks everybody actually i was a PG student doing my research work on 3D analysis of a laminated plate using FEM in the process got a doubt whether an analysis has to be carried out separately for fracture or not. And also is there any compulsion in going for fracture while analyzing a plate or else just finish at calculation of stresses.
