    How incresing substeps results in POST1?

    Hi! I have made a transient analysis (full method) with load step 10 sec. and time step 0.002 sec. With "CONFIG, NRES,5000" I get all substeps in the Time HISTORY POSTPROCESSOR (POST26), but I get only the first 800 substeps (up to 1.6 sec.) in the GENERAL POSTPROCESSOR (POST1). Does a command...

    FSI, contained fluid,must also use contact elements?

    Thanks for the interest cbrn. I have given the viscosity of the water (0.0011 Ns/m2) with VISC real constants for FLUID80, but however it has little influence, I think that my boundary conditions are correct to simulate a fluid structure interaction (no friction need),unfortunately nobody dealt...

    Now I'm hopeless, help!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

    FSI, contained fluid,must also use contact elements?

    I am studying the behaviour of a water tank "blocked" at base; for the steel structure I have used SHELL63 elements, for the fluid FLUID80 elements. At boundary I have imposed that nodes of the fluid and those of the structure have the same displacement in the direction normal to the interface...

    Thanks cbrn, with your help I solved the problem!!!!

    How read modal analysis results?

    Thanks cbrn, but I have not understood as set up OUTRES and as go to read the results on file.

    How read modal analysis results?

    I have done a modal analysis, but I do not know how to read the results, I find only the frequencies, but I need participating mass for every mode. Help!

    interaction fluid structure FLUID80-SHELL63

    I'm studying the behaviour of a cylindrical tank full of water, I have used elements SHELL63 for the steel structure and elements FLUID80 for the water,at boundary I have coupled nodes(coincident, but separates ) of the fluid and the structure only in the direction normal to the tank's...

    How couple two nodes in only one direction.Help!!!!!!!!!

    Thanks for interest Stringmaker, I have already solved using CP command. To the next one!!!!

    How couple two nodes in only one direction.Help!!!!!!!!!

    I'm studying the behavior of a cylindrical tank full of fluid, for the cylinder I use elements SHELL63 and for the fluid elements FLUID80. Ansys help says:"Fluid element at a boundary should not be attached directly to structural elements but should have separate, coincident nodes that are...

    how apply accelerogram in Ansys?

    Thanks cbrn and Stringmaker I believe to have resolved the problem, finally! Regards Michele

    how apply accelerogram in Ansys?

    Cbnr,your help has been me very useful! A last thing, when I create the table in which I will insert the text file, must I give Var1 = Time, Var2 = UX (in my case I had to assign displacements in x direction varying in the time), that is, for Var2 I had to give name of my variable according to...

    how apply accelerogram in Ansys?

    Yes, I can integrate my data twice with respect to time obtaining displacement vs. time, but someone can explain me how create a table with, we say, 2 columns and 2000 rows, where the first column contains values of the time and second contains values of displacement and then how apply this...

    how apply accelerogram in Ansys?

    Thanks cbrn.Unfortunately I'm using Ansys CivilFEM 9.0, so I can only use displacement vs time, but my problem is the same: insert a displacement vs time point table in a transient analysis and obtain time history. Help please!!!

    how apply accelerogram in Ansys?

    Thanks still, Stringmaker.I have exactly 1536 points accel.-time on a notepad file (txt), they are a record of earthquake, therefore there is no function describing them. Someone says it's not possible giving accelleration vs time in Ansys, but only displacement vs time in a transient analysis...

    how apply accelerogram in Ansys?

    Thanks for interest Stringmaker.Yes I mean acceleration vs time, in Italy we call it "accelerogramma".I am beginner of Ansys and I don't know how to apply a table of 2000 points acceleration vs time at the base of my structure in a transient analysis,I need a time-history response. A help would...

    how apply accelerogram in Ansys?

    I want apply accelerogram to the base of my structure in a transient analysis, it's possible?
