Problem in Command DUMPEMFIELDS and DUMPFIELDS

Summary

By email from Dou Gouliang

When I use the command "DUMPFIELDS" and "DUMPEMFIELDS" , the opal_2.4 shows the error (annex 1):

Error> *** Error:
Error> Internal OPAL error:
Error> Assertion 'idx.i < num_gridpx_m - 1' failed.
Error> idx.i = 118, num_gridpx_m - 1 = 118.000000
Error> in
Error> /afs/psi.ch/user/g/gsell/private/src/OPAL/src/src/Classic/Fields/FM3DH5BlockBase.h, line 163

I have checked my inputfile ,and there is no wrong experssion. The detailed experssion is :

DUMPEMFIELDS, COORDINATE_SYSTEM = Cartesian, X_START= -0.8, X_STEPS=1601, DX= 0.001, Y_START=-0.25, Y_STEPS=501, DY= 0.001, Z_START=-0.02, Z_STEPS=41, DZ=0.001, T_START=0,T_STEPS=1, DT=0.1 ,FILE_NAME="FIELDEM-MAPXYZ.dat";

When I try to split the original output area of X into two parts, opal can output the corresponding two parts normally. First change X_STEPS to 117, and then change X_START and X_STEPS to -0.215 and 204.

And I re-ran another cyclotron simulation and got the same error, except idx.i changed to 14 .

and later

I ran it again in a newer version of OPAL(opal-2022.01) and found the same errors. In particular, I used OPAL-2022.01 as a Linux binary package from the official website.
