simple text output

Beitrag von Dexter22 »

I've setup a simple simulation of a beam element No. 25,
1 element,
2 nodes,
Constrained at node 1 in all 6 dof
Under a force in the -ve z axis at node 2

I solve and get:

"Z88ER done
linear solver Z88R done
Solver successfull"

in z88r.log

displacements file with odd entries:


output file Z88O2.TXT: displacements, computed by Z88R V15.0B

Firstly, what does IND000E+000 mean?

Secondly, does anyone have any suggestions to fix this unreported error?

Hello Dexter22,

-1.#IND000E+000 means that this value is indeterminate. Windows says "-1.#IND" while Unix says "NaN" which means "not a number".

Which solver did you use? Did you set all parameters correctly? Could you provide us with your project files, so we can have a deeper look at your problem?

Kind regards,
SHautsch

Ok

I'm running from a command line in the win/bin folder

z88r -t -choly
then

Re: simple text output

Beitrag von mifris »

Hello Dexter22,

your example has seven boundary conditions and you wrote only two in the z88i2.txt file! :-)
Therefore your example is statically undetermined.
And yes, there is no need of z88int.txt for beams, but the solver needs the information, that there is a file calls z88int.txt.

Best regards,
M. Frisch

Ah ok, I made a silly mistake, thanks.

I've re-run the simulation but now I don't get any nodal forces, only displacements.

Do you have any more suggestions?

Dexter

Hello again,

hmm, that`s weird. Can you please send us your project folder?! (z88aurora-at-uni-bayreuth.de) That makes it easier for us to have a look at your example. :-)

Re: simple text output

Beitrag von Dexter22 »

Thanks for your help.

like you said via email, it was the orientation control point that was wrong. I'm not sure why though:

In my case, I had a beam 25 element from (0,0,0) to (100,0,0)[on the x axis]

The point 3 (control point)

1 - Does not work at (0,1,0) [not on the x axis]
2 - Does work at (0,0,1)[not on the x axis](as expected from the theory manual.)
3 - Does not work at (1,0,0) [on the x axis] (as expected from the theory manual.)

So now my question is why does the control point not work when it is on the y axis? In the theory manual, the only requirement is that it doesn't lie on the axis of the beam element (in this case the x axis)
