Using Analytics to Remove Risk and Reduce Costs from Lending and Servicing Practices

Would your organization like to lower the costs of technology, make more efficient decisions, and capitalize on unrealized opportunities? This could mean writing more mortgages, providing better customer service, or perhaps servicing the business better. Mortgage providers struggle to find, extract, and analyze data trapped in proprietary data formats, PDF files or reports. Rather than retype data or wait for IT to help, organizations can use powerful, self-service tools to get the data you need—when you need it—to make decisions that are right for the business.

An Analytical Approach to Financial Crimes Rules Creation and Optimization

Recent studies from leading financial institutions show that financial fraud continues to rise at alarming rates. According to Experian, credit and debit card fraud has risen over 60% in the first half of 2019. Although Millennials are highly targeted (an 80% chance of being a target of fraud), no one is immune from criminal activity. Home grown fraud rules, based on in-house subject matter expertise and observations, are commonly used to counter fraud attacks as well as other financial crimes, such as Anti-Money Laundering. Altair offers an industry leading approach to augment/adjust these rules based on actual analytical models. The benefit realized is that fraud analysts can update rules without needing to turn to highly utilized resources such as data scientists.

Multidisciplinary Workflow to Assess Modal Fatigue Results of a 4-Cylinder Crankshaft Using AVL EXCITE, OptiStruct and FEMFAT

The crankshaft of an engine is a highly dynamically loaded component that is continuously optimized and optimized in terms of design and production technology. In order to be able to reproduce this in the simulation, the essential influences must be considered. This includes the dynamically behaviour in combination with the engine, the material properties and the application of the loads and their transfer to other parts (bearings). The modal approach has established itself as a proven method here, whereby a modal basis is determined in the FEM so that the crankshaft is integrated as a flexible body in the MKS model of the engine, and so that an entire engine run-up can be simulated. The modal participation factors are obtained from the MBS simulation, which are used together with the modal stresses for the safety factor calculation. This workflow requires the combination of different simulation tools. The challenge is to organize the data transfer between the tools efficient and correct. In this example, the workflow is realized using OptiStruct from Altair for FEM calculation, EXCITE from AVL as MKS tool and FEMFAT from Magna Powertrain ECS as Fatigue solver. This makes it possible to simulate a complex engine run-up with consideration of the ignition bearing forces and to calculate the fatigue life of the crankshaft in FEMFAT. This webinar, details of the simulation workflow of the 4-cylinder crankshaft will be presented and the effects of several influencing variables on the fatigue life will be studied.

Simulation of Cavitating Flows and Gas Bubble Transport with DSHplus

The occurrence of cavitation negatively affects the performance of hydraulic systems. The impairments range from increased noise levels to severe and life-limiting wear of machine parts. Cavitation in hydraulic systems can be prevented by early integration of one-dimensional fluid power simulation software into the design process. In this webinar, FLUIDON’s piping expert “RohrLEx” explains how cavitating flows can be simulated with the updated component models of DSHplus. The improved models enable the user to analyze all relevant types of cavitation – vapor cavitation, gas cavitation and pseudo-cavitation – as well as the associated phenomenon of gas bubble transport. To illustrate the workflow when simulating a cavitation-endangered and/or gas conveying system with DSHplus, two exemplary cases are presented and discussed.
