1. 1. A High Order Finite Difference Method for Simulating Earthquake Sequences in a Poroelastic Medium

   University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

   Author : Kim Torberntsson; Vidar Stiernström; [2016]
   Keywords : numerical analysis; numerical methods; numerical modeling; SBP-SAT; finite differences; high performance computing; geophysics; geomechanics; poroelasticity; fault mechanics; induced seismicity;

   Abstract : Induced seismicity (earthquakes caused by injection or extraction of fluids in Earth's subsurface) is a major, new hazard in the United States, the Netherlands, and other countries, with vast economic consequences if not properly managed. Addressing this problem requires development of predictive simulations of how fluid-saturated solids containing frictional faults respond to fluid injection/extraction. READ MORE

3. 2. Numerical simulation of the Dynamic Beam Equation using the SBP-SAT method

   University essay from Uppsala universitet/Institutionen för informationsteknologi

   Author : Vidar Stiernström; [2014]
   Keywords : Dynamic beam equation; finite difference methods; stability; boundary treatment;

   Abstract : A stable boundary treatment of the dynamic beam equation (DBE) with two different sets of boundary conditions has been conducted using the summation-by-parts-simultaneous-approximation-term (SBP-SAT) method. As the DBE involves a fourth derivative in space the numerical boundary treatment is highly non-trivial. READ MORE
