In order to predict farfield noise created by the flow over complex geometries, high-fidelity flow simulations based on the Lattice-Boltzmann solver PowerFLOW are used in conjunction with the acoustic analogy solver PowerACOUSTICS. Since the flow needs to be spatially and temporally well resolved, the simulations are usually carried on a large number of computational cores for adequate turnaround times. This paper provides the background on the two-step methodology and gives an overview on aero-acoustics computations in aerospace, ranging from an isolated airframe component to the entire aircraft system. © Springer International Publishing AG 2017.

BURLINGTON, Mass., Nov. 30, 2016 (GLOBE NEWSWIRE) -- Exa® Corporation (NASDAQ:EXA), a global innovator in simulation software for product engineering, today announced financial results for the third quarter fiscal 2017, which ended October 31, 2016. (1) Calculation based on amounts presented in the accompanying financial statement tables “We continued our momentum in the third quarter and delivered revenue that was in the middle of our guidance range and profitability that was above the high end of our guidance range,” said Stephen Remondi, President and Chief Executive Officer of Exa. “With license revenue increasing 14% from a year ago, we continue to drive a shift in mix to higher-margin, recurring license revenue. Strong renewal activity in the quarter sets us up for a healthy finish to fiscal 2017 and start to fiscal 2018. We are pleased to achieve this performance while making important investments that will enable us to further capitalize on our position in the market and continue our growth.” Based on information available as of today, Exa is providing fourth quarter and fiscal 2017 guidance as indicated below. The above guidance assumes an exchange rate of 1.06 US dollars per Euro and 110.0 Japanese yen per US dollar for fiscal year 2017. An explanation and reconciliation of historical and forward-looking non-GAAP measures presented above, including revenue on a constant currency basis, adjusted EBITDA, non-GAAP operating income (loss), non-GAAP net income (loss) and non-GAAP net income (loss) per diluted share, to the comparable GAAP measures is provided below and in the attachments to this press release. Non-GAAP Financial Measures  To supplement our condensed consolidated financial statements, which are presented on a GAAP basis, we disclose revenue on a constant currency basis, non-GAAP operating income (loss), non-GAAP net income (loss), non-GAAP net income (loss) per diluted share and Adjusted EBITDA. These non-GAAP measures are not in accordance with, or an alternative for, amounts determined in accordance with generally accepted accounting principles in the United States. The GAAP measure most comparable to revenue on a constant currency basis is GAAP revenue. The GAAP measure most comparable to non-GAAP operating income (loss) is GAAP income (loss) from operations. The GAAP measure most comparable to non-GAAP net income (loss) and Adjusted EBITDA is GAAP net income (loss).  The GAAP measure most comparable to non-GAAP net income (loss) per diluted share is GAAP net income (loss) per diluted share. A reconciliation of these non-GAAP financial measures to the corresponding GAAP measure is included below. We define revenue on a constant currency basis as GAAP revenue, adjusted to reverse the impact of changes in the average exchange rates of currencies in which our international operations generated revenue and incurred expenses. We define non-GAAP net income (loss) as net income (loss), excluding the after tax impact of non-cash, stock-based compensation expense and the amortization of acquired intangibles. We define EBITDA as net income (loss), excluding depreciation and amortization, interest expense, net, other income (expense), foreign exchange gain (loss) and benefit (provision) for income taxes, and we define Adjusted EBITDA as EBITDA, excluding non-cash, stock-based compensation expense. Our management uses these non-GAAP measures when evaluating our operating performance and for internal planning and forecasting purposes. We believe that these measures help indicate underlying trends in our business, are important in comparing current results with prior period results, and are useful to investors and financial analysts in assessing our operating performance. For example, our international operations generate revenue and incur expenses that are denominated in foreign currencies. These amounts could be materially affected by currency fluctuations. Our principal exposures are to fluctuations in exchange rates for the United States dollar versus the Euro, British pound, Japanese yen, Chinese yuan and Korean won. Changes in currency exchange rates that are beyond our control can significantly affect our consolidated results of operations. We believe that disclosure of our revenue on a constant currency basis is useful as an indicator of demand for our solutions independent of the influence of currency exchange fluctuations. Management considers Adjusted EBITDA to be an important indicator of our operational strength and the performance of our business and a good measure of our historical operating trends. The non-GAAP financial information presented here should be considered in conjunction with, and not as a substitute for, or superior to, the financial information presented in accordance with GAAP and, in particular, should not be considered a measure of our liquidity. There are significant limitations associated with the use of non-GAAP financial measures. Further, these measures may differ from the non-GAAP information, even where similarly titled, used by other companies and therefore should not be used to compare our performance to that of other companies. Investors should carefully consider the attached reconciliation of these non-GAAP financial measures to the comparable GAAP financial measures.

Cavity modes taking place in the rims of two opposite wheels are investigated through Lattice-Boltzmann CFD simulations. Based on previous observations carried out by the authors during the BANC-II/LAGOON landing gear aeroacoustic study, a resonance mode can take place in the volume between the wheels of a two-wheel landing gear, involving a coupling between shear-layer vortical fluctuations and acoustic modes resulting from the combination of round cavity modes and wheel-to-wheel transversal acoustic modes. As a result, side force fluctuations and tonal noise side radiation take place. A parametric study of the cavity mode properties is carried out in the present work by varying the distance between the wheels. Moreover, the effects due to the presence of the axle are investigated by removing the axle from the two-wheel assembly. The azimuthal properties of the modes are scrutinized by filtering the unsteady flow in narrow bands around the tonal frequencies and investigating the azimuthal structure of the filtered fluctuation modes. Estimation of the tone frequencies with an ad hoc proposed analytical formula confirms the observed modal properties of the filtered unsteady flow solutions. The present study constitutes a primary step in the description of facing rim cavity modes as a possible source of landing gear tonal noise. © 2014 Elsevier Ltd.
