the punctuation token ')' error!
 
I changed my variables in groovyBC as this
Code:

"p_3=p0_3/pow(1+(gamma3-1)/2*magSqr(U)/(gamma3*R*T),(gamma3/(gamma3-1)));"
//"p_2_last=800000;"
//"p_2_first=1600000;"
"p_2=810000;"//(p_2_last-p_2_first)/(c2r-c1r)*(t_mappedr-c1r)+p_2_first

why this error occurred?
Code:

Time = 0.000118

When in doubt, simplify and/or isolate and conquer:
Code:

"p_3_part1=1+(gamma3-1)/2*magSqr(U)/(gamma3*R*T);"
"p_3_part2=(gamma3/(gamma3-1));"
"p_3=p0_3/pow(p_3_part1,p_3_part2);"
"p_2=810000;"

If this works and the other doesn't, then it's possibly a bug in the parser (the algorithm that interprets the expressions) that groovyBC uses.
