    Python script: each time write output w/o overwrite

    Hi there! I have a script which can write *.csv file with name lets say 1.csv I'm going to preform parametric study, so ODB name will be same. If do so script will just overwrite my 1.csv file and that's it. How to change a script so it will check existed name (number) and add +1 instead...

    simple problem with UMAT

    Hello Dears! could you help me please. I wrote a small umat subr, but it works doesn't correctly I have 2 steps Dens=7800 for Emodulus i use next eq. E=Dens**2.5 at first i define DDSDDE, stess, strain, strain energy denity, and parametr S if S < some value then Ddens=7800 and then...

    subroutine young's modulus time-dependency

    Hello everyone! Could you help me please with a simple problem. I am a PhD student working in the biomechanics field and I should use some "smart" materials. I am doing simulations young's modulus time-dependency I have never written a subroutine code I'd like to use some equation [see...

    Moving pressure with DLOAD subroutine

    Mr. Bartosz, Dear Sir! I mean dynamic analysis in Abaqus/Explicit! I simulate railroad tracks for dynamic analysis see no reason to use a moving load in static analysis could you show an example of using VDLOAD, I would be very grateful to...

    Moving pressure with DLOAD subroutine

    help me please why this sabroutine does not work when dynamic analysis? at static works and does not work with dynamic I really need it to work in a dynamic analysishttp://files.engineering.com/getfile.aspx?folder=43f7f3b3-bb51-4456-93c7-a6b86c904238&file=dload.rar

    Simple problem &amp; subroutine &amp; usdfld

    Thank you so much, Mr. akabarten. It helped me. The main task - to build bone model with variable over the thickness elastic modulus. In the article (http://www.asbweb.org/conferences/2010/abstracts/102.pdf ), I saw something similar but for the density there also used usdfld What do you think...

    Simple problem &amp; subroutine &amp; usdfld

    I'm trying to simulate a plate with different thickness elastic modulus. I use subroutine and usdfld For a rectangular plate I did. But for a circular plate need to use a cylindrical coordinate system, because I want to simulate a different modulus of elasticity in the radial direction I...
