Nays2DH

Nays2DHとは?

Nays2DHは,河川における流れ,河床変動,河岸侵食の計算を行うために開発された,一般曲線座標で境界適合座標を用いた非定常平面2次元流れと河床変動計算の解析用ソルバーです。

Nays2DHは,従来iRICに搭載されていた平面二次元ソルバーのNays2DとMorpho2Dを統合し,より多機能でユーザーに要望に幅広く対応することを目指して開発されたソルバーです。
Nays2DH version1.0では,Nays2DとMorpho2Dで使われてきた流砂量式を選択可能とし,Nays2Dの特徴である合流点モデル,河岸侵食モデルなどと,Morpho2Dの特徴である掃流砂-浮遊砂混在場の混合粒径モデル,上流端の土砂供給量の変化,掃流砂層モデル,固定床モデルなどを結合させています。本バージョンでは,Morpho2Dが有する浸透流モデルが組み込まれていないなどの改良点はありますが,その点は随時更新していく予定です。

計算結果のアニメーションはこちらをご覧ください ( https://i-ric.org/videos/ )。

なお,Nays2dHの簡易版でPythonコードによって書かれたNaysMiniも公開されております.Pythonコードはすべて公開されておりますので,学習用などにご使用下さい.

CONTACT/HIRE A PROFESSIONAL HACKER TO RETRIEVE LOST CRYPTO ASSETS: VULNERABILITY SAVER. I was devastated. After sinking my life savings of $346,700 into a shady crypto trading platform, I watched it vanish. Fake recovery firms piled on, scamming me further with empty promises and upfront fees. First, Elite Crypto Recoveries promised 90% return for a $5,000 upfront fee. They ghosted me after payment. Then Blockchain Saviors demanded $10,000 for advanced tracing, only to disappear. I fell for three more fakes, losing another $20,000. Each time, slick websites and fake testimonials suckered me in. I felt foolish, broke, and hopeless. Depression set in, I’d worked 20 years as a teacher to save that money for retirement and my kid’s college. One sleepless night, scrolling forums like Reddit’s r/cryptoscams, a post caught my eye: Vulnerability Saver saved me from ruin. Intrigued, I researched. They were forensics experts specializing in blockchain analysis. Their site, detailed success stories. Skeptical after my ordeals, I emailed them. They responded promptly, no pressure. They explained their process. I provided transaction IDs, wallet addresses, and scam details. Their team, cyber investigators, blockchain analysts sprang into action. Using forensic software, they traced funds through mixers and anonymous wallets. It wasn’t easy, scammers had laundered via DeFi protocols. But Alpha Spy Nest’s expertise shone. They collaborated with law enforcement contacts, freezing suspect accounts. Days passed with updates: We’ve identified the endpoint wallet. Then the breakthrough, negotiating with exchanges to reverse transfers. Finally, the email: Funds recovered. $316,700 back in my secure wallet. Tears flowed. Vulnerability Saver restored not just my money, but my faith. If you’re scammed, skip fake recoveries and contact them. Life’s brighter now; I’m investing wisely, thanks to their guidance. Don’t give up, real help exists.

HOW VULNERABILITY SAVER HELP ME TO RETRIEVE MY LOST ETHEREUM In early summer, I purchased two VIP passes to a highly anticipated championship game. The seller insisted on payment in Ethereum, claiming it was a secure and fast method for high-value transactions. After some hesitation, I agreed, transferring approximately $6,600 worth of Ethereum directly to their provided wallet address. I received what appeared to be legitimate electronic tickets, complete with seating information and barcodes. When the day of the game arrived, my excitement quickly turned to disappointment. Upon presenting my tickets at the entrance, the scanning system rejected them as invalid. Multiple venue staff confirmed they were counterfeit, and the seller’s contact information had already gone dark. I realized I had been scammed. Feeling helpless, I began researching options for cryptocurrency fraud recovery and discovered VULNERABILITY SAVER . They specialized in tracing stolen digital assets through blockchain analysis and working with exchanges to recover lost funds. I reached out, providing them with every piece of information I had: the Ethereum transaction hash, screenshots of my communication with the seller, and copies of the fake tickets. Within hours, VULNERABILITY SAVER confirmed that my payment could be traced through the Ethereum blockchain. They explained that although blockchain transactions are irreversible, stolen funds often pass through centralized exchanges where regulatory compliance can force the return of assets if they’re identified quickly enough. They assured me they would act immediately. Over the next three weeks, VULNERABILITY SAVER kept me updated with detailed progress reports. They tracked the stolen Ethereum through several intermediary wallets, eventually identifying it as having been deposited into an account at a known cryptocurrency exchange. Acting on my behalf, they coordinated with the exchange’s fraud and compliance teams, providing evidence of the theft and linking it to my original payment. To my relief, the exchange froze the account containing the stolen funds. After verifying the legitimacy of my claim, they initiated the return process. In less than three weeks from my initial contact with VULNERABILITY SAVER, the full $6,600 worth of Ethereum was transferred back to my wallet.
