PAFEC error collection

**ERROR** FAILURE IN SUBROUTINE R09895
ATTEMPT TO ACCESS SWITCH21883 IN MODULE 113
BUT THIS MODULE ONLY CONTAINS10008 SWITCHES

This occurred when PAFBLOCKS were used with node numbers
that did not exist (the referenced nodes were of very large values)

-----------------------------------------

ERROR IN CALL TO R09895
SWITCHES MODULE 2058 IS NOT IN BASE

fixed by:

adding FRONTAL.SINUSOIDAL.SOLUTION

------------------------------------

*** ERROR *** THERE ARE 0 DEGREES OF FREEDOM THIS IS INSUFFICIENT FOR A VIBRATION/BUCKLING PROBLEM.

This occurred with a PZT / acoustic simulation. Viewing node numbers to check which node
to apply a voltage to, showed the acoustic node numbers only, with default settings.
I set direction 4 on the acoustic node, with the result that no meaningful boundary condition was
set.

Mesh parts, structure showed a different node number. Changing to this number fixed the error.

--------------------------------------

*** ERROR *** THE INSTANTANEOUS SIZE SO FAR CALCULATED, IS 9999.
THIS IS GREATER THAN THE MAXIMUM 9998

in Phase 4. Big job. Fixed by adding,

PHASE=4
MAX.FS.RECORD=100000

to the control module. Default size is 10,000

-----------------------------

Phase 4: Acoustic FE with BE.

 ***ERROR*** IN R25875
 SAME NODE IN BOTH ACOUSTIC BOUNDARY
 AND FINITE ELEMENT TOPOLOGIES
 NODE 101 B.E. 1 F.E. 51
 NODE 105 B.E. 1 F.E. 50
 NODE 105 B.E. 1 F.E. 51

Set the BE to group 1, the acoustic FE to group 2 and do:

COLLAPSE
GR1 GR2 COUP
1 2 3

to separate the nodes.

-----------------------------

***ERROR*** IN ROUTINE R25868
NO COUPLING FOR FLUID BOUNDARY ELEMENT FACE
111 112 113

Occurred with CONTROL module option,

TOLERANCE=10E-12

Changing to

TOLERANCE=10E-6

fixed this.

----------------------------------
Phase 7

CHANGE IN DEFINE RESPONSE
AT TIME 0.0000000E+00 FOR DOF 43
0 *** A BLOCKED FRONT SOLUTION HAS BEEN REQUESTED ***
0 THE BLOCK SIZE IS 891112
***ERROR***
FAILURE IN R09810
THERE ARE NO SCRATCH MODULES AVAILABLE


A result of leaving MASTERS in a FRONTAL.TRANSIENT analysis.

-------------------------------

Phase 4.

**ERROR** FAILURE IN SUBROUTINE R09895
 ATTEMPT TO ACCESS SWITCH   71 IN MODULE  177
 BUT THIS MODULE ONLY CONTAINS    0 SWITCHES

This was a thermal job.  I left SINE.LOADING, RESPONSE, FRONTAL.SINUSOIDAL.SOLUTION, COMPLEX.SOLUTION, VISCOELASTIC in.  The error changed to,


 **ERROR** FAILURE IN SUBROUTINE R09895
 ATTEMPT TO ACCESS SWITCH   25 IN MODULE  113
 BUT THIS MODULE ONLY CONTAINS   12 SWITCHES

Removed HARMONIC.NUMBER=0.  No change.
Removed LAMINATES and ORTHOTROPIC modules: Nope.
Removed PIEZOELECTRIC module.  Nope.
Removed FREQUENCIES.FOR.ANALYSIS.  Nope.
Removed MODES.AND.FREQUENCIES.  Nope.
Removed FULL.DYNAMICS.OUTPUT.  Nope.
Redefine MATERIALS for thermal:  Nope.
Added a different temperature elsewhere in the model.  Bingo.
