The default is zero. SET DAMP VISCOUS MODE 0(default)/1 The mode is set to 0 or 1 for all newly created contacts. DAMP VISCOUS MODE 0(default)/1 The mode is set to 0 or 1 for all contacts in the range. Below is the mode description. Mode 0 (default): The viscous damping force is added AFTER checking contact bond breaking criteria and frictional slip criteria. Viscous damping in this case applies to the built-in contact models (the Linear contact model or Hertz-Mindlin contact model)or the user-defined contact models. Mode 1: The viscous damping force is added BEFORE checking contact bond breaking criteria and frictional slip criteria. Viscous damping in this case applies to the built-in contact models (the Linear contact model or Hertz-Mindlin contact model). NOTE that users who want to make a user-defined contact models with a viscous damping term within their code should include the viscous damping term in the calculation of contact shear force and set it to variable "cs_force" in FdBlock (in the updated contmodel.h). Also, mode 1 ("SET DAMP VISCOUS MODE 1" or "DAMP VISCOUS MODE 1") should be set o avoid extra damping forces added externally to the user-defined model. (2) Add solve ratio in cycle information during SOLVE. 3.00-176 08/06 (1) BUG fix: (-083-116-176) (a) Fatal error with the ductile model : a user-defined contact model. 3.00-177 09/02 (1) Add information of Maxfric(on/off) from Print Wall Prop command (-084-116-177) (2) BUG fix: (a) Wrong message in PRINT CELL after SAVE RESTORE and BALL command (b) Retieve 0 for User-defined object pointer in extra array (CPPUWC option) (3) Add Mag(Udvect &) to get magnitude of Udvect class (CPPUWC option) (4) Add Udata::pointer_type() = 105 for User-defined object (CPPUWC option) (5) Add Udata::Uremap(Uobj *uop) function for User-defined object (CPPUWC option), see example below class Uobj_2 : public Uobj { }; class Uobj_1 : public Uobj { private: Uobj_1 *uobj1; Uobj_2 *uobj2; // .... }; void Uobj_1::read(Ufile &fi) {{ uojb1 = (Uobj_1 *)Udata::Uread(fi,uobj1); uobj2 = (Uobj_2 *)Udata::Uread(fi,uobj2); //.... } void Uobj_1::remap(void) { uojb1 = (Uobj_1 *)Udata::Uremap(uobj1); uobj2 = (Uobj_2 *)Udata::Uremap(uobj2); // .... } 3.00-178 10/14 (1) Add command : DELETE WALL #1 <#2 #3 #4 ...>, DELETE WALL #1 to #2 <#3 to #4> ...

In the case of SOLVE RATIO ### (with SET SOLVE_RATIO AVERAGE) command, the average unbalanced force is calculated as sum of the absolute values of all out-of-balance force components for all balls divided by number of balls that have at least one non-fixed translational degree of freedom. 3.00-181 12/22 (1) BUG fix: (-085-116-181) (a) Wrong stress value in measurement circle (sphere) with Ball-General Wall contact 3.00-182 01/14 (1) BUG fix: (-085-116-182) (a) Udata::clump_head(), Udata::b_clump() (CPPUWC option) (2) Add Udata::Uwrite() and Udata::Uread() for Uclump (CPPUWC option) 3.00-183 01/19/04 (1) BUG fix: (_085-116-183) (a) Udata::cl_list(), Udata::cl_add()(CPPUWC option) 3.00-184 01/26/04 (1) BUG fix: (_085-116-184) (a) Udata::c_nstrength(), Udata::c_sstrength()(CPPUWC option) 3.00-185 02/25/04 (1) BUG fix: (_086-116-185) (a) Save\Restore problem : Table Plot Item (b) FISHCALL "pre_cycle" with uniform density scaling mode 3.00-186 04/06/04 (1) BUG fix: (_086-116-186) (a) Data communication between process with Parallel Bond in Parallel option (Parallel Option) 3.00-187 05/12/04 (1) BUG fix: (_086-116-187) (a) Contact recovery after deleting permanent clump 3.00-188 06/16/04 (1) BUG fix: (_086-116-188) (a) SET DISK t command (PFC2D, in the case of non unit thickness of t) 3.00-189 07/15/04 (1) Update clump logic in the case of iteration fail of angular velocity calculation (_086-116-189) (3D only) 3.00-190 09/01/04 (1) BUG fix: (_086-116-190) (a) Contact detection between a Flat wall and Balls in the case that the wall poistion is on a cell boundary. 3.00-191 09/21/04 (1) BUG fix: (_086-116-191) (a) Udata::w_rvel() for 3D (CPPUWC option) 3.00-191 09/21/04 (1) BUG fix: (_086-116-191) (a) Udata::w_rvel() for 3D (CPPUWC option) 3.00-192 03/10/05 (1) BUG fix: (_086-116-192) (a) Udata::c_prop() (CPPUWC option) 3.00-193 05/12/05 (1) BUG FIX: Save/restore problem if using CPPUWC. 3.00-194 11/14/05 (1) BUG FIX: Fixed problem when printing FISH arrays containing character strings. ======================================================================== EOF: pfc300pre.TXT
