Run batch mode analysis in MAPDL

  Hi, everybody
  
  I'm trying to run a static analysis in MAPDL's batch mode (BM). But first, I tried to run it in interactive mode (IM). The macro is the next:
```
CDREAD,DB,'MATLAB2APDL','cdb',,'','' ! Import the file
CPINTF,ALL,0.0001,                   ! Merge conincident nodes
/SOLU                                 
SOLVE   
SOLVE                                ! Needed in interactive mode 
```
  The batch file code its this simple line:
```
SET KMP_STACKSIZE=2048k & "C:Program FilesANSYS IncANSYS Studentv194ANSYSbinwinx64MAPDL.exe" -b -i "COINNODE.mac" -o "test.out"
```
  I add a second SOLVE in order to run the analysis in IM, and works. This doesn't affect the execution in BM, that keeps giving the next issue:
  
  *** NOTE *** CP = 7.644 TIME= 10:46:20
  
  The Distributed Sparse Matrix Solver is currently running in the
  
  in-core memory mode. This memory mode uses the most amount of memory
  
  in order to avoid using the hard drive as much as possible, which most
  
  often results in the fastest solution time. This mode is recommended
  
  if enough physical memory is present to accommodate all of the solver
  
  data.
  
  Distributed sparse solver maximum pivot= 1.966963211E+10 at node 4147
  
  ROTY.
  
  Distributed sparse solver minimum pivot= -21.2980198 at node 2075 ROTX.
  
  Distributed sparse solver minimum pivot in absolute value=
  
  2.030464831E-19 at node 7037 UZ.
  
  NUMBER OF WARNING MESSAGES ENCOUNTERED= 301
  
  NUMBER OF ERROR MESSAGES ENCOUNTERED= 1
  
  ***** PROBLEM TERMINATED BY INDICATED ERROR(S) OR BY END OF INPUT DATA *****
  
  I didn't encounter this problem in IM. What should I do to correctly run the analysis in BM?

  I was able to get it working.
  
  The attempts I made were:
  - A second SOLVE;
  - Executing the /NERR command as its written in the Command Reference and in the URL written below;
  - Executing the /NERR command, a little bit unorthodox, but this option worked.
```

  I'm still can get the Von Misses stress. Somebody know why?
