In a case structure.....

If temp>800 celsius, then

     pressure=100*e^(10t)

where t is time varies at a rate of 100 ms.

else pressure=10 bar

but t should increase gradully by 100 ms or 0.1 sec

This appears to be a continuation of your earlier thread: http://forums.ni.com/t5/LabVIEW/XY-graph-using-formula-node/td-p/1846609

Please stick to the original thread.

Why do you have two separate case structures, with the same selection logic?

The input to your express formula node is not wired.

This may help.

[Jathin]

can you please explain what is the need of using date/time function and double penetration in the above problem

[.aCe. · Accepted solution]

That is to calculate the the elapsed time. The first one takes the time when you start the vi, the one inside the loop takes the current time and the substract just determines the elapsed time from start. I assume thats what you wanted.

The double conversion (i assume) is just to avoid a coercion dot.

after seeing the solution ace presented I was able to re-read the OP and find every element captured.  Some magic decoder ring you have there ace!

On the other hand- remove both convert to doubles and see if you get coersion dots
