co-relation between practical and virtual conditions
Altair EmployeeHi,
In Radioss solver completed a test of run time 0.3 second in 15 hours.
In practical condition we have to run the same test for 3 hrs.
How could we obtain the same output of practical condition in virtual?
Is it essential to run the analysis for 3 hrs(180 min*60 sec=10800 seconds)?

Hi Prakash,
I have similar query in case of vibration of shaker table.
Vibration Analysis is running successfully and behavior is also correct.
Now according to practical conditions we run the vibration test for 2 to 3 hrs, wherein frequency of shaker table is 3Hz and amplitude is 1 inch(25 mm).
According 3Hz frequency, we calculated time for 1 cycle=1/3 sec which is 0.333 sec.
For a complete run of one cycle, analysis is taking about 12-15 hrs.
But as in physical condition test run is for 2hrs, for me the number of cycles becomes 2400 cycles. This means my total run will be for approx. 28800hrs.
Kindly suggest how we can reduce the total test run time, at the same time co-relate practical and virtual test runs.
Thank-You
Hi Tushar,
depends on the test.
Say for example you want to do a drop test of a ball from 10mts height. For this case you dont have to drop the ball from 10mts in virtual.
You can calculate the velocity from a particular height (like 0.01mts) and run from there.
