Flowsheet Simulation of Solids Processes

Corotational Simulation of Deformable Solids

The classical formulation of large displacement visco-elasticity requires the geometrically nonlinear Green tensor. Keeping track of the rotational part of strain permits alternative formulations, that allow the tensor to stay linear, and at the same time maintaining rotational invariance. We replace a recently proposed heuristical warping technique by the application of the polar decomposition...

Designing a Process Flowsheet

The appearance and form of piping and instrumentation diagrams (P&IDs) have changed little over time, despite decades of technology improvements. A P&ID created 60 years ago on the drawing board, using ink pens on linen sheets, describes a process the same way as one created today using modern computer-aided design (CAD) software. P&IDs continue to be fundamental references for any process faci...

Horizontal decomposition of triangulated solids for the simulation of dip-coating processes

In dip-coating processes a three-dimensional object, e.g. an entire car body, is dipped into a liquid bath. In order to simulate such processes, the space surrounding the object is decomposed into the so-called flow volumes, for which each intersection with a horizontal plane is connected. At any time the liquid’s surface then has a unique level within such a flow volume, which greatly simplifi...

Measurement-Based Interactive Simulation of Viscoelastic Solids

Animation of viscoelastic solids in entertainment and medical applications as well as scientific simulation can be improved through observations of real world objects. This paper presents a method for simulating viscoelastic solids in real-time for visual and haptic display along with a method for determining the parameters of the the underlying model from automated physical measurements of rea...
