The macros were created to simplify my work, most of the times to
save me from frustration.
I really really hate to do the repeated monotonamous tasks, so thats
the
reason I like hypermesh better, In hypermesh most of the repeated
meshing or modelling tasks can be automated usign Hypermesh libraries
and Tcl/Tk. Not just meshing tasks but also the templates to export and
import FE models from/to your inhouse FE-solver etc etc.....I think
most of the functionalities in HM can be customised.
As I mentioned these macros were created inbetween my busy work,
creating
programms whenever something is required, so they are error prone and
not
tested at all but what the heck it does the work.
So do not test thesse things for various inputs and trivial cases
just
use it for what it is intended for, better est modifiy it for your
requirements.
I think engineers time is very valuable they should not waste time and
money clicking hundreds of nodes one by one, the time can be better
spend in modelling, interpreting results and optimising the solution.
So macros help a lot in that whether in HM during meshing or in NATRAN
and ABAQUS during analysis procedures. I hope somebody find it
usefull
My first customisation is a Property Browser:
From HM7.0 altair introduced a component browser to help the things out, but I always wanted a property browser (For Nastran) to list various PBAR properties and I also wanted to know what is the diameter of the PROD or PBAR properties [atleast approximately] to get an idea of what is the dia. usually when the data is changed between hands and softwares the name of the properties changed so there is no way you can preserve the property names, so it will be prudent to have a property brwoser which provides you the list of all properties and CARD type like PBAR, PROD etc, material dependencies of those properties and the diameter, if it is Circular or sectional dimentions if it is a rectangular section.
So Here it is the property browser Download the Property Browser Here
As I have said these macros were created just in minutes. Most of
times
I do not have a luxuary of time and enough patience to create from the
scratch,. This browser is based on the HM material browser provided by
the Altair from HM7.0. I modifed it fot property listing. As you can
see
it can find out the sectional dimentions if it is a Circular or a
rectangular
section.
From HM7.0 altair provides a Materila browser which list the material
properties, as given below
I have a question for you, do you honestly think I can use this browser without getting mad. I can not beleive they did not test this. It is good one by Altair but the display makes it useless and irrtiating So I have just modifed the original program to display the numbers [E, mu etc] with some fixed format, as given below.
Don't you think mine looks better ;-).
Let say I have some 20 components from a Catia geomtery and the
mid-surfaces needs to be created for each one of those. Do you think
the
current methos of creating Mid-surface by component by component will
work
for people like me. Moreover you have to select the Normal direction [
ok recent release have that eliminated]. For example I have
component
A-Pillar B-Pillar and Roof and I wanted to create Mid-surfaces in a
single
click for all these three components also I wanted the respective
mid-surfaces to placed at new components Namesly MS_A-Pillar, MS_Billar
and MS_Roof. Beleive it or not it makes my life very simple.
