If tensile stresses develop across the frictional interfaces a warning will be printed with this information. Under tension, the surfaces of the fault elements are no longer in contact and the shear stress becomes zero. Under these conditions it may be difficult for the solution to converge. This is not a problem when only a few elements have tensile stresses but can be a large problem when there are many.
A job may run without ever converging. This happens because several fault elements see-saw smal amonts of slip back and forth between iterations. Under such conditions, it may be neccesary to kill the job. Examination of the run information provides critical information on whether a job is being productive or has stalled because of tensile stresses across several elements and see-sawing slip. Version 2.0 of FRIC2D automatically stops after 100 iterations to prevent run-away jobs.
Here is an example of the run information for the sample data file of figure 4.4. Note: there is no frictional slip along the faults in this example and so the number of iterations is 1.
The loading step is now 1 out of 2. Starting fracture growth increment #1 of 2 Iteration: 1 The loading step is now 2 out of 2. Starting fracture growth increment #1 of 2 Iteration: 1

Boundary lines will be blue, faults are green and fractures are red.
At the beginning of a FRIC2D output file the following data are listed:
The loading step is printed out at the begining of each set of data.
On the request of the user, i.e. bdata=1, FRIC2D outputs the basic data, and stress and displacement data of individual boundary elements.
Boundary element basic data are those entered by the user. For each boundary element, a line of basic data is given in following order:
Since the basic data doesn't change for each loading step this data is only printed in the first step. This serves to reduce the file size which could become large if there are hundreds of elements and many loading steps.
Stress and displacement data for each element are listed in a FRIC2D output file in following order:
The output of fracture data in a FRIC2D output file is similar to the boundary element data. When the user needs fracture data, i.e. fdata=1, FRIC2D will output the basic data, tractions, displacements and displacement discontinuities of individual fractures.
The output of basic fracture data is similar to that for the boundary element data. For each fracture, a line of basic data are listed in following order:
FRIC2D outputs stress and displacement data of individual fractures in a similar manner to boundary element data as follows:
The output of fault data in a FRIC2D output file is similar to the boundary and fracture element data. When the user needs fault data, i.e. faultData=1, FRIC2D will output the basic data, tractions, displacements and displacement discontinuities of individual faults.
The output of basic frault data is similar to that for the boundary and fracture element data and is only printed in the first loading step. For each fault, a line of basic data are listed in following order:
FRIC2D outputs stress and displacement data of individual fractures in a similar manner to boundary element data as follows:
Observation points are defined by observation lines. FRIC2D outputs the coordinates, displacements and stress at specified points in following order:
The stresses without gravity are provided to assist with analysis of the just the tectonic stress field in the model.
At the end of each loading step the fault elements that slipped in that loading step are listed. The fault name is given followed by a list of elements on that fault which slipped.
The output data from FRIC2D for the problem given in Figure 4.4 is as follows:
*********************************************************************** TITLE1: Splay crack growth along two faults; TITLE2: with a nearby kinked fracture; SYMMETRY: none Data will be written from the following iterations: 1 Boundary Data:..........no Fracture Data:..........yes Fault Data:.............yes Observation Line Data:..yes Superpose Gravitational Stresses ....no 0.250000 = Ratio of horizontal:vertical gravitational stresses 2600.000000 = Rock Density 4 = number of straight-line boundary segments 1 = number of fractures 2 = number of faults 5 = number of observation lines 0.200000 = poisson's ratio 10000.000000 = young's modulus 2.500000 = Fracture Toughness 10.000000 = Tensile Strength 0.001000 = Convergence Tolerance =============================== DATA FROM LOADING STEP #1 OF 2 =============================== RESULTS AFTER 1 ITERATIONS: ============================ If 1 = 101 convergence was incomplete and some interface elements do not match the solution. In some cases this may be resolved with a lower tolerance. If some faults are slipping a lot (>0.5m) the locally high strains will prevent convergence. In this case try smaller boudary loads/displacements or simpler fault geometry. ========================= DATA FROM ITERATION #1 ========================= -------------- FRACTURES --------------

LOADING STEP #2 OF 2 =============================== RESULTS AFTER 1 ITERATIONS: ============================ If 1 = 101 convergence was incomplete and some interface elements do not match the solution. In some cases this may be resolved with a lower tolerance. If some faults are slipping a lot (>0.5m) the locally high strains will prevent convergence. In this case try smaller boudary loads/displacements or simpler fault geometry. ========================= DATA FROM ITERATION #1 ========================= -------------- FRACTURES --------------
