Merlin User’s Manual Draft 3 ABSTRACT MERLIN is a ﬁnite element program with capabilities for both two- and three-dimensional • Static and dynamic stress analysis, • Steady state and transient heat transfer analysis, • Steady state and transient seepage ﬂow analysis, and MERLIN has been designed to perform nonlinear stress analyses and linear heat transfer and seepage ﬂow analyses. MERLIN can be used to perform linear stress analyses, but does not sup- port a load case capability, making automated superposition of stresses from diﬀerent load cases or individual components of a load case impossible. Nonlinear stress analyses are supported through an incremental-iterative solution strategy. Whereas MERLIN was originally written for the nonlinear fracture mechanics analysis of concrete dams, it has numerous features which make it an attractive program for other stress analysis (crack propagation simulation in particular). Merlin-II is identical to the original Merlin, however it does support smeared cracks and its development was not supported by EPRI. A separate manual contains numerous examples of data ﬁles for MERLIN. This manual, including latest updates, is available on line at the following Web sites: http://civil.colorado.edu/~saouma/Merlin and http://civil.colorado.edu/~saouma/Spider Merlin User’s Manual Draft 4 Merlin User’s Manual Draft 5 ACKNOWLEDGMENTS MERLIN was developped by by Drs. Jan ˇ Cervenka (ˇ Cervenka, J. 1994), and Ron Reich (Reich 1993) at the University of Colorado under contract from EPRI. Prof. V. Saouma was the principal investigator. Currently, Dr. Eric Hansen is working on Merlin. The smeared crack model of MERLIN-II was implemented by Cervenka Consulting.
