<br>Dear all,<br>
<br>
I am a student at the University of connecticut doing research on
cliamate variability. I am new to GrADS, and I am having problem using
the (UDF) psichig. I think I have sucssesfuly installed the UDF but I
am developing priblem from the start. When I try to run the test file "
t.psichig.sh" I get the error massage below,<br>
<br>
Non-numeric args to numeric operation<br>
Error occurred on line 3<br>
In file t.psichig.sh<br>
<br>
Line 3 is the test run of "t.psichig.gs" now when I try to run "t.pschig.gs" i get the error massage below,<br>
<br>
Syntax Error: Invalid Operand <br>
'psi' not a variable or function name<br>
Error ocurred at column 1<br>
DISPLAY error: Invalid expression <br>
Expression = psi(all,ua,va)<br>
<br>
Can somebody help in identifying the problem and the possible solution.<br>
<br>
And is there another way of getting the velocity potential without using the "UDF- psichig"<br>
<br>
Thank you in advance<br>
