Analysis stopped after timepoint 0
Altair EmployeeHello!
At first a big thank you for the help yesterday.
An Introduction in my Problem:
I´m trying to analysis a Ring which should displaced by tools. The boundary condition of imposed displacement is given by a diagram in 20 timesteps.
I want to know the stresses inside the ring after the tools are driven back in the zero point.
Yesterday I found out, that there is no Runtime defined for Radioss, so he stops the simulation after the timepoint zero.
But the runtime is defined, Radioss should stop at timepoint 20, not after 0.
Edit:
The really annoying point is, that my input data in control cards (picture 3) is not considered. You see the view of input file after analysis (picture 4)
Edit 2:
The time steps I typed of couse in (pic 5)

Altair EmployeeGood morning,
yes, the names are identicly chosen. Picture 3 should only showed what I typed in the control cards.
It works now, that Radioss uses the engine parameter: picture 2, if I exported the engine file, deleted the cards and imported them back ( i don´t know why, but it works)
But although he has the right parameter, he still stops the analysis after timestep 0. picture 1
It makes me a bit perplex that the inputfile of radioss (picture 2) contains no timesteps: /impl/dtini 0.1
Altair EmployeeHi,
Please share the starter and engine files.
Altair EmployeeHey
I uploaded it in your Dropbox.
Altair EmployeeHi,
Please maintain unit consistency in your model.
i am not sure whether the units of time used is secs or milli seconds, but try to work on the run time.
Altair EmployeeThank you very much.
The Units I used:
Length: millimetres
time: seconds
Mass: Megagram
Force: Newton
Pressure: Megapascal
velocity: millimetres/ seconds
Altair EmployeeHey there!
Okay I get it. It does work now.
Hi,
From Pic 3 and Pic 4, I can see that both are two different files.
The name of the file is different in both the pictures.
Make sure the starter and engine file names are same and also RUN/<starter file name> is shown in the engine file.
If starter file name is run1_0000.rad, then engine file name should be run1_0001.rad and the commad for RUN will be RUN/run1//
