1. 519619 MARUNTE RIFLEX 3 6 6 Release notes date 2009 03 18 page 9 of 9 e Velocity and acceleration of slave dofs rigid node connection The velocity and acceleration computations for slave dofs have been modified to be 5 3 B6 10 in accordance with the Newmark beta relation This may give small changes to results e Contact springs Linearized dynamic analysis Apply spring stiffness for all nodes in contact the seafloor even if the nodal status is sliding from static analysis This may give small changes to results e Export static results for visualization by SIMVIS Specifying export of element responses enables visualization of the incremental loading configurations by the computer program SIMVIS after completion of the static analysis In the case of an error termination results from all iteration during the last load step are also exported 6 2 A4 e PLOMOD The number of environmental variables needed by PLOMOD has been reduced to two RIFLEX_HOME and GPGS_DEVICES If the environmental variable RIFLEX_PLO_INCA is not set PLOMOD will search for the Inca command file plomod inca on the RIFLEX_HOME etc catalogue If the command file is not found PLOMOD will prompt the user to specify the file If the environmental variable RIFLEX_PLO_LOGO is not set PLOMOD will search for the logo file RIFLEX_HOME etc logo dat If no logo file is found the logo will be set to MARINTEK The2. 6 Release notes date 2009 03 18 page 6of9 6 Error corrections and improvements 6 1 Corrections and improvements included in RIFLEX 3 6 1 e Results to ascii or binary file DYNMOD CRSO In case of kinematic isotropic hardening the stored results were for the previous iteration step e CRS3 non dimensional hydrodynamic coefficients The specified non dimensional hydrodynamic coefficients were taken as dimensional coefficients e Enforce nodal base vector system to be orthonormal The requirement to orthonormality has been made stricter This may give insignificant changes to results e Coupled analysis STAMOD The computed stiffness contributions from SIMO forces were erroneous This could cause the static solution to diverge Normally this gave insignificant changes to the static equilibrium configuration if the solution was found e Flex joint The applied flex joint stiffness was erroneous when tabulated moment rotation relation was specified Error in stiffness for dofs subsequent to the first dof with tabulated stiffness 6 2 Corrections and improvements included in RIFLEX 3 6 3 e Contact forces boundary change and use of sparse matrix formulation DYNMOD This error concerns the options Elastic contact surface Pipe in pipe contact and Boundary change including winching The structural velocity and acceleration may be inconsistent when the contact changes from one node to another system dependent The er
