What is different besides the use of scientific notation on one scale and full numbers on the other?
Both Static solution has load 20kn
Capture1 screen show max Von Mises 51, so 235/51=4. So I can still rais up load for around 4 times.
Capture2 screen show max Von Mises 5.175e. So I have already exceeded load for around 2 times.
And, in real world I think beam HEB180 can able to hold much more then show Capture3, around 9kn!

Capture 1 shows Von Mises stress max of 51,754,848, or 5.176e+007 (e+007 means move decimal point 7 places to the right)
Capture 2 shows Von Mises stress max of 5.175e+007, which is the practically the same.
Count the decimals carefully, and you will see. Note that the circled values in Captures 3 and 4 are not close to being equal, since one is e+007 and one is e+008, which means one is 10X the other.
I don't follow, what is the problem?
The only difference between Capture1 and Capture2 is that Capture2 uses scientific notation and Capture1 uses floating notation.
Capture2: 5.175e+007 = 51 750 000 N/m^2
Capture1: 51 754 848 N/m^2
Yield strength of material: 235 000 000 N/m^2 (2.350e+008) so about 4,5 times higher than your calculated stress.
If you increase the amount of decimals for the schientific notation result you will probably be very close to 5.1754848e+007
In capture 3 you changed the load to 9000 and the result is 2.329e+007 = 23 290 000 N/m^2 so about 10 times below yield
So what is the problem?
Crap, I have missed +007 or +008 of decimals. I was really confused what am I doing wrong. No problem any more, I get it now.
Thank very much for help!
