The integrand I calculate is very complex and location-related. It takes a lot of time to go through a two dimensional region step by step using "while" loop structure, so how to use NIntegrate In parallel? I am a complete beginner in Mathematica.
Can't help you unless you post your code, preferably using the Code Sample icon.
Thank you, I solved the problem.
Can you use inequalities to describe the region you want to integrate over? In that case, you could use NIntegrate just once
In[1]:= NIntegrate[ Boole[Or[(x - 3)^2 + y^2 <= 1, (x + 3)^2 + y^2 <= 1]], {x, -100, 100}, {y, -100, 100}] Out[1]= 6.28319
Maybe this helps.
Would you please give me a hand? I'm not yet familiar with the software and language.
